Sounds to me like your Photoshop preference file has gotten corrupt (not that uncommon). Removing and reinstalling PS doesnt change/overwrite the (corrupt) preference file, as it is not located at the same location as Photoshops program files. To delete that file, start Photoshop (and while it is opening); hold down Alt, Ctrl, and Shift keys (Mac: Command, Option, Shift). A dialog box will appear asking if you wish to delete the preferences file. The message you got is normal when PS is first installed, then goes away after the first few times Photoshop is opened. It is not an error message but just informing you that Photoshop would prefer to have its scratch disk on a separate physical drive from Windowss swap disk. BTW: Adobe has said that putting PSs swap file on a partition on the same drive as the OS, really does nothing but waste disk space. It needs to be on a separate physical drive to see any performance improvement. SWAMP
