I use WinXP Pro SP1 as my main operating system. Memory modules = 288MB I do a lot of photo enhancement work using JASC Paint Shop Pro 8 (PSP8). My problem is that after a few adjustment to a photo, everything "locks up," and Windows Task Master tells me that CPU = 100%. I then must close PSP8 down. I can switch to a Windows ME operating system, and I don't have any problem, but WinXP is my Internet OS, so I use it most often. What is the solution, if any, to this problem? Do I need to add more memory? Thanks , Tom Do you want to signoff PCBUILD or just change to Digest mode - visit our web site: http://freepctech.com/pcbuild.shtml
