Bug in rendering icons on editing button bars

[chandragor]

Editing the button bar shows wrong icons for some programs, usually taken randomly from programs in the current bar or on previously edited bars.

This happens for both 32 and 64 bits version, tested on Windows 7 (32 and 64 bits) and Windows 8 64 bits.

This bug was introduced in TC 9.10, as it was not present in TC 9.00 nor in any previous versions.

This bug is in visualization during editing only. The icons are saved correctly in the button bar.

I will check it, thanks.

If it can help, icons often change by moving the cursor on them or by scrolling them left or right.

It seems like a rogue pointer problem inside the TListBox / LCLListBox controls.

It seem to occur randomly but I can reproduce it with for example this butonbar (with Windows 7 standard programs) http://madsenworld.dk/tcmd/win7amd64_1g_eng.bar

1. Load the bar and open it for editing.
2. In the field next to the "Add"/"Delete" buttons click on the third icon (Ease of Access Center) and then on the sixth icon (On Screen Keyboard) - and you will see the error.
3. Click back and fourth between the third and the sixth icon, the icons shift to the the previous icon by itself.
4. The icons in the "Icon" field show the wrong icons.
5. Clickiing the "Icon file" field fixes the icon in the top, but NOT the icons in the "Icon" field. The other icon in the top (3 or 6) is changed to the wrong one.

You might have to restart TC and then reload the buttonbar for the bug to occour.

This should be fixed in TC 9.20 beta 1, please test it!

Confirmed fixed in TC 9.20b1 (at least with the test file in my previous posting)
