Hello again, cheers for your thoughts about this. I've since found that it's only my project .jpg's that I backed up onto dvd that are having this problem. I can take a .jpg from the web and it works fine, I can then alter it in PS and again it's fine, I can even create something new in PS and it works perfectly but none of the Photoshopped .jpg files that are on the dvd that I used to back up my final year project before I upgraded my OS to 64-bit flingin' flangin' work! Oh well, I've got my project proposal to worry about for now, I rekon I'll be busy changing file types this weekend!! Hope your cold gets better Steve and I'm glad you got your trousers to stay up!! Later, Mat.
