Thanks Johnny for your reply, I wonder if anyone knows why these files keep turning up? I have Cakewalk on my computer, the imageiio files has the same icon as cakewalk,(which is for playing Midi files) and when opened they open up the cakewalk programme !!
First thing is to go into 'File Types' under tools > Folder Options (in Windows Explorer) And change the file association back to the Ulead Photo prog. It could be something to do with Cakewalk that is causing this problem, not the Ulead app. This should check that part out.
