Well that didn't take long. Updated video drivers didn't correct.
Because the problem is in a specific area (possibly a common control) and the rest of the screen is not affected makes me think that area needs to be investigated.
Does anyone know if the text editing area is a common "thing" (how about that technical term) that would be used my Word, Excel, SQL Mgmt Studio, and Outlook?
What would be a good way to investigate that "thing"?
