Need Help with my XP-Style menu

Hey guys. I have some function which allow for XP-Style and Office97-Style owner-drawn menus which I have posted at www.planetsourcecode.com. Problem is, there's a small glitch when using XP as someone reported, and I'm running win2000 so I don't know what's causing it. A sample of the glitch can be seen at www.quixotix.com/tmp/XPMenu.jpg. If you can help me figure out what is causing this glitch I'd be super-stoked.

Thanks guys... Oh! The code can be downloaded at planetsourcecode.com...

If that link doesn't work just go there and search for "Quixotix" in the .NET code.

Thanks in advanced.

I've tried this on XP with no problem . my guess would be G card would affect in such issues. (I think so )

you should try this with no bugs.
