Hi all. STILL trying to figure out why WIN500 will not work on my Toshiba notebook. I have the Satellite u305-S2812 running Windows 7. Whenever I start WIN500, I get the loading screen, and then the dialog box that WIN500 has stopped and Windows is checking the problem. It always winds up closing down. Meantime, on my Dell Studio Slim with Windows 7, I have no problem. This is driving me nuts!
