Hello

What properties you have changed in this control?

Can you show an example please?

Please find attached a demo project. You have to set Ctl3D := False to reproduce the bug.

While testing, I came across another ununsual behaviour, by the way. Right-click on the button of the sDirectoryEdit, and a pop-up dialog appears (see attachment 1, is this as designed?). Select 'Insert Unicode Control Character -> LRM'. Once you've closed the dialog and right-click on the button again, you'll either end up with an AV (see attachment 2) or a tiny and empty pop-up (see attachment 3). Can you please check? I've attached a compiled version of the demo application as well, as the last two errors I've described only appear randomly (either with the modal form still open, or after closing and reopening it).

Serge, the access violation I described in post no.3 is still there in v. 7.43. Can you check? Thanks!

I can't reproduce it unfortunately.

Can you show me a callstack for the error? Can you share your PC with me?

Steps to reproduce:

1. Run test.exe in Debug Mode from the Delphi IDE

2. Click on Button 1

3. Right-click on button of sDirectoryEdit1 on the modal Form2

4. Choose the 'Insert Unicode Control Character' menu item from the popup menu

5. Click on LRM, closing the popup menu

6. Right-click on the button of sDirectoryEdit1 again

7. Crash

Error message: “First chance of exception at $76C4FBAE. EAccessViolation at address FEEEFEEE. Read of address FEEEFEEE.”

Sometimes the whole IDE locks up and I can't kill the running test program anymore – not even through the Windows Task Manager. I have to stop the Delphi process to gain control again.

If you run the test program outside the IDE, you will get the behaviour I've described in post #3.

The PC is a development machine and not hooked up to the web, sorry.

I can't reproduce it still, but I'll try more on other machines.

You have this issue under Vista only? Can you check it please?

Bug only occurs in Vista, not in XP.

Reasons are same as in the topic about a print dialog. I will search other systems.

Or maybe you can give me access to your PC for debugging?

Serge, I finally found out what is causing the AV.

Steps to reproduce:

Open ASkinDemo

Remove PopupMenu1 from the PopupMenu property of MainForm

Recompile

Click on the 'Skin options' tab and then right-click on the button of the SkinsDirectoryEdit

Click 'Insert Unicode control character' -> 'LRM'

Close popup menu

Right-click on the button of SkinsDirectoryEdit again

Access Violation (you will have to kill both Delphi and the demo in the Task Manager afterwards!)

I have already a system where I can reproduce a problem.

This issue will be solved in the next release.
