I use ACDSee Classic as an image viewer but I have a reoccuring problem where opening a file from the Windows Explorer window result in the above error message. This message does not occur when ACDSee is already open and I try to open the image the same way. Also f I set windows to use another program to handle images it works fine. Uninstalling and reinstalling ACDsee does not help, a complete reformat will fix it however. After I reformat it will work for a while then this will randomly just start happening again. Its kind of annoying so I was wondering if anyone has a suggestion that would allow me to fix the problem. Thanks.
