I recently upgraded to 2008 and I have this problem after certain commands. For example with erase, I start the command and click the object and hit enter (right click) and my cursor disappears. It is rather annoying because you have to "wiggle" the mouse whenever you complete the command. I also noticed while a command is active and I move the mouse the title bar will flicker. I made sure I have the latest display drivers and my windows updates have all been installed. My monitor is a 20.1" LCD flat panel hooked up through DVI. I am running Windows XP SP2.
My specs:
2.13 GHz Core2 Duo
2 GB ram
NVIDIA Quadro FX 1500
Please, I need help before I go insane
