Hi, thank you for your feedback.
I am investigating the issue. We observed the bug ourselves for a (very) few times. What I fear is that the bug is not in Qt, but in Windows Mobile itself and is triggered by the way we wrap the win 32 API into our Qt API. Actually once the menu is created (And while no changes are done.) we do nothing to the menu besides calling DrawMenuBar() and handling the WM_COMMAND messages from Windows. I will try to reproduce the bug properly/reliable and investigate it. Hopefully there is a proper way to circumvent this bug. Some questions: Are you doing anything to the menus when/while the bug appears (disabling/enabling, checking/unchecking, adding/removing of sub-menus), or does the menu remain completely static? Do you have any chance to try to reproduce the bug on Windows Mobile 6? Did you try whether modifying the menu (Adding an item.) "repairs"the status? Best Regards, Thomas Hartmann George H.
