They are files I used without problems in PS 6.0 and Win NT. I have to clarify that I have these problems even if I only select the files in Windows and I don't have the time to try to open them in Photoshop. They can be existing files, dowloaded files (for example a DAZ template) or archived files that I could open or tranfser on my hard disk without trouble prior the change to Win 2000. Btw Is there a particular reason I should try the demo of PS 6 rather than the complete PS6. Thanks
