Problem with VB6 ComboBox with style "DropDown List"

I have tested my application developed with VB6 on Windows 11 for which we use a manifest to improve the presentation.

VB6 ComboBox with style "DropDown List" visually display nothing when they have the focus.
VB6 ComboBox with style "DropDown Combo" display well when they have focus.



I noticed that if I open the executable by selecting it in Windows Explorer and starting it with an Enter, the focus is displayed.



I've done some research and I can't find the difference between running an executable with a double-click or with a click and an Enter.

I thought my problem was only with Windows 11, but I noticed in my tests that I also have the problem in Windows 10.

When I run my executable without the manifest, everything works fine.

Thanks
