NV drivers in Windows 7

I was just wondering if anyone else had any problems with Windows 7 after installing NVIDIA drivers? Specifically, after I installed NVIDIA drivers on my system, the context menu from the desktop is really laggy. I removed the Nvidia Control Panel option from the context menu and it reacts the way it should. When Nvidia Control Panel option is in the context menu though, it takes 2-3 seconds to pop up the context menu.

I'm having problems with some OpenGL-based apps, but that's about it.
