I never knew you could remove just nview. It used to work well (several workstations and OS's ago), I really liked having multiple virtual desktops. Not as important now with dual screens but I would still use it if it didn't hose up. I will delete is since I can't use it. Surprising how your machine was faster without the graphics driver than with the driver and nview. I swear software has become so bloated and layered today that we are wasting 90% of the CPU cycles.
