I hope somebody can help me with the following problem.
I simply use CheckMenuItem on a item in the regular main menu
previously created with SHCreateMenuBar. So far so good, that all works
like it is supposed to.

Through another menu item I open a settings dialog. As soon as I leave
this settings dialog, the previously set check mark in the main menu is
gone. Further attempts of calling CheckMenuItem seem to be alright when
I debug them, but the check mark doesn't appear again til I restart the

Any thoughts on that issue ?
Somebody ran into the same problem ?
