Thank you, gaz and Drew. I might try to take pbcopter's advice and update the graphics card drivers from the Toshiba site. At any rate, I'll try not to worry about what's not broke.
Unless you can document that similar problems are being experienced by a significant number of other customers, I'll agree with PCBoyGeorge and assume the problem's with your computer (or you). Bye, bye!
We just downloaded Windows 7 and we love it. I have two questions, though: 1) The base score on my computer is 3.1; the Gaming Graphics is 3.1 and the Desktop Performance for Aeros is 3.4. These are the lowest scores-- the highest is a 5.1 in Disk Data Transfer Rate. Is this okay for a 2007...
