gdi glitches

Has anyone of you experienced glitches with GDI+ using it within Windows XP? I'm trying out this ownerdrawn context menus but the LinearGradientBrush object and DrawRectangle function and probably others as well, give problems. They seem to not complete their jobs. The menu selections appear incomplete, and I fear that it has something to do with the mouse.

The SolidBrush, however, seems to work fine when used to fill a rectangle. But I'd really like that gradient. :p This is driving me nuts since I've been struggling with it 3 full days now.

I'll attach the original source code link to the idea.

NOTE: Seems to work fine on Win 98, Me, NT4 and 2K. But not with XP.
