Hello again! 
I'm sorry to come back to this one, but its actually beginning to cause a little difficulty. I now have several variables in an EA which just won't delete, and keep saying they're used in non-existent blocks. Therefore my variables list is getting a little too long..!
Is there a work-around for this you could suggest?
Thanks again.
OK. But I haven't knowingly hidden anything. What's the procedure to hide something? And that doesn't explain why it thought a block existed which I hadn't created.
Oddly enough, the problem has now gone away. As far as I know I didn't do anything to make it go! Could something have been hanging around in memory which eventually died away?
In order to try to get around this, and just in case it was something that had gone wrong in my code, I opened a new project entirely. However, I find that I still have the problem, and now the error message which appears says a variable which is to be deleted is in use by blocks with numbers I did not create!
I'm experiencing a problem in the local version.
I have 41 variables and 50 blocks.
I created a temporary block and a variable which the block refers to. Later on I deleted the block, but the local version still seems to think the block exists, and won't allow me to remove the variable. I then checked in MetaEditor, and the block is indeed absent as a "find" does not locate the block number #123.
Have you noticed this behaviour before? Is there a way of clearing this?
All seems fine now. Thank you for your great support on this software!
Previously I could rename an .mq4 file created in fxDreema from aaa_v1.mq4 to aaa_v2.mq4, then import the v2 file into fxDreema local and it would store the EA inside fxDreema as well as the .mq4. Now it isn't stored in fxDreema. Is this expected? This was a useful method of creating a new version of an EA in the absence of a "file/save as" function.
For anyone reading this (!) I'm now going to recommend that you don't optimise or back test in Linux/Wine. You can use a virtual machine in Linux to do these tasks, but it must be a Windows one. My tests have shown inconsistent results using Linux/Wine, but not using Windows virtual machines.
I believe there are plenty of people using Linux/Wine to trade using MT4, but don't back test or optimise outside of Windows.
Sorry! 
Just as a thought for a work-around for back testing in MT4 on Linux/Wine, how about using the "Time filter" block to specify the start and end point for when your EA will be active. I haven't really tested this, but presume you'd need to use "local time" and not "server time" and "Start time mode = Component format" in the block.
However, if your data is large, it could take time for the tester to reach your start date. This is true for data from Alpari, for example, which starts with daily data from 1971, and took several hours to reach my 2000 start date.
Lastly, remember to OFF tick the "Use date" and "Visual mode" boxes in the MT4 back tester.
Hope I've got this all correct!
I'd like to update this. The MT4 tester has a problem on Linux/Wine. See here: http://appdb.winehq.org/objectManager.php?sClass=version&iId=2893&iTestingId=47131 and here: http://www.forexfactory.com/showthread.php?t=252050. Use the Virtual machine you installed in Oracle VM Virtual Box for back testing!
This is very strange. I made a modification to another unconnected block, and now I'm getting just 1 trade. At least its working!
I'm still struggling with this - sorry!
I'm using "Check trades count" < MaxTrades (a variable which is set to 1).
I'm still getting 2 trades taken. I can't understand it!
Could I make a wee suggestion regarding Linux and Wine? I too run MT (MT4) on Linux, and apart from the speed slider in the tester being difficult to use, all seems 100%. With regards to fxDreema, I suggest installing Oracle VM Virtual box and running a virtual Windows session. I'm using XP SP3 because its easy and very cheap!
I enjoyed your last post a lot! I laughed out loud too! I must also congratulate you on your use of English. There are many people in Scotland who could learn from you! Even worse, there are many who couldn't point to Bulgaria on a map!
Thank you for "033a"! Seems to be OK now.
Thank you also for the background information. Most interesting. I was aware of UAC issues. I'm not using it.
Thanks again.
Of course! You are quite right - again!
Thanks.
I'm sorry you are having such trouble with your MySQL hosting people. That's a real nuisance for you. Anyway, it isn't putting me off fxDreema! And hopefully others will understand too.
I hadn't really thought about the backspace button vis-a-vis browser actions, and of course that makes sense. I only noticed as I was trying to edit the block heading and was expecting to erase character left at the time. I wonder if it should be disabled from doing the browser back function in fxDreema just to avoid user confusion?
I'm a bit worried about moving back from 033 to 032 having had that "corruption" error message from Metatrader earlier today. I'll take a snapshot of my PC and then do it. That way I've got an easy return to where I am now! I do really need the ability to edit the block header, and 032 had a problem with && in a custom code block, if you recall! So I'm slightly between a rock and a hard place!
Thanks for your great support for fxDreema.
OK. I've now tried this with the "Check trades count" block. Again, I have a variable called "MaxTrades" set to 2. Inside the block I have "Compare <= lower than or equal to", and "Orders count" pointing to the "MaxTrades" variable.
Unfortunately on my USDJPY pair I still get at least 3 trades running when there should only be one or two.
Yes. I was/am compiling with MetaEditor as well as fxDreema.
I seem to have got round the corruption issue. I reverted to an earlier snapshot of my PC when build 031 was installed. I then installed build 033 over it, and the corruption issue seems to have gone away.
That said, I also deleted the .ex4 files, just leaving the .mq4 ones. Then I loaded the EAs by calling them in to fxDreema using "Load project from file", and re-compiled using MetaEditor.
What hasn't gone away is that I can't edit the titles of the blocks. Right click produces the option, but there is no cursor in the heading. This feature worked fine for me in build 032.
In addition I've noticed that if I hit the backspace key in fxDreema I'm dropped out and back to the login screen.
Are you anywhere near resolving the login problem? Its taking anything up to 1/2 an hour to log in, clicking every 15 seconds or so!
Just to let you know, I have completely removed build 032, searched the registry for "fxdreema" entries and removed them. Tested a backup copy of my EA in MT4, which compiled and ran it fine. Then re-installed 032, edited my EA, re-compiled it, and MT4 says its corrupted.
