One can easily reproduce it with your own examples (e.g. ComandBarControls). It doesn"t happen on all systems, but it does happen on Windows Server 2016, for example. Only switch to theme Windows11 light

Hello,

I've installed Windows Server 2016 and VB6 for test.
Test CommandBarsSample 24.2 and 24.3 versions. Switch theme to Windows 11 light/dark.

Any problems not found.

Can you attach video with you crash?

All tested examples show the same error. I have now created the example using C# (32bit) and installed it on the network. This does not cause a crash on any system, but there is a repaint problem on all terminal servers.
If you build the same example with VB6, it will cause a crash on all terminal servers, but it will work fine on the other machines (including the repaint). We program in C++, but with ActiveX it behaves in the same way as the VB6.

Please check these applications on Terminalserver. They are VB6 builds from your samples (style directory must exists). If I change to theme Windows11 there is a problem, other themes work fine.

Yes, we use RDP. But version 24.2 works under the same conditions even over RDB without errors
