Hi Folks, (I'm posting this here as I need system help not application software help) I've been using Photoshop 7 and Photoshop Elements 5 for some time now with no problems. I've recently got a full version (tryout) of CS2. It installed without a hitch but when I launch it, everything appears to be OK (I get the message saying you have 28 days left etc) but it then freezes. I can't access any of the menus or even click the toolbars. The only way to get out is via Task Mgr. I know the program is OK as it works ok on two other computers. I therefore need to track down the problem on mine. Here are some details: I have a DELL 9200 with a Duo Processor 2.4GHz, 4MB of RAM, 500GB system disc (RAID 0 stripe) so I don't think it's a performance problem! I'm running XP Pro SP2 plus all current updates. When I launch CS2 I can see from Task Manager that the Photoshop.exe process appears and uses about 2-8% of cpu during loading. However, as soon as it is loaded, when I would expect the cpu usage to reduce to zero again, it rises to 50% and stays there and the application immediately says "not responding". I need to find out what is causing this so any help will be much appreciated. I also have Photoshop 7.0 and it works perfectly. I have compared all settings and set my PC for "Performance" (programs) and increased the paging file to 3x RAM size but still the same. Thanks in advance. Regards.
