After running openGL windows maximizes and minimizes programs differently?

I am running XP Pro on a NVIDIA GeForce 2 GTS/GeForce2 Pro. This may seem like a small problem, but after running a program that uses OpenGL, the maximize and minimize is not smooth anymore. This is true for IE and AIM…pretty much any window that is open. I have the most updated drivers from NVIDIA. It seems miniscule but after a while it seems to slow my machine down.

I had the same problem when i was running 2kPro also. It would happen after I ran a Shockwave application, but that was fixed in SP2. However, when running screen savers that use openGL such as Helios, and when running Quake 3, this problem occurs. Any ideas? Thanks.
