Context Menu Graphics Bug on Vista

[Dlyan]

I found something weird since I installed jZip on Vista.
It's about explorer context menu more precisely about the graphics. When jZip is installed the context lose its Vista's Aero style...

Please fix.

Doesn't happen on Vista x64, not on my system anyway. But then I don't have jZip in my context menu!
