Hi Robert. I feel your pain. It's happening to me as well -- on all Office programs. Have you noticed it on Excel and/or PowerPoint as well? I've been at this for 3 weeks now, with my highly skilled I.T. guy and we are stumped. We've replaced the video card twice, updated drivers twice, power source once, checked for heat problems, and upgraded from Office 2007 to 2010. He's convinced it's a software problem. The problem is still present but much more tolerable in Windows Classic mode. Today I'm going to systematically uninstall and reinstall all add-in programs. All my programs are up to date. I've Googled this topic to death and am beyond frustrated.

Out of curiosity, what type of monitor do you use?

Paul - given my description, any ideas?
