Provider2 just helped me stop 2 programs auto installing. Now the system seems to be working well. I have just reinstalled Adobe Photoshop CS2. It appears to install okay. When you start it up it appears to start okay, the splash screen appears and goes through the start up, that disappears and the normal working page appears, but as soon as I click on any menu,tool etc. it goes blank with the top left corner of the working page showing Adobe Photoshop (not responding). I also tried a "repair" from the unistaller, but no joy. For info: I am working on a Dell Dimension 9150 I am running XP pro sp3. AV is AVG and firewall is Comodo. I have never been able to get PShop working on this computer, so I don't think it is a PShop problem. I have stacks of disk space, and 2Gb RAM. Any suggestions greatly appreciated.
