mugsworth, I guess Im still not making myself clear, or Im just too dense to understand what you are trying to tell me. (Which is VERY possible, LOL.) In response to your last advice: There is NO offending file. When the Photoshop APPLICATION loads it places a 48 meg file on disk in spite of the available RAM. Photoshop History states are NEVER saved with files when the file is closed. Therefore, there would never be anything to Purge when any file is first opened. Thank you for your kind advice anyway. No need to respond. I think we burned this one to the ground. Regards, Pinto
