I already had Office 2003 installed on my XP Pro machine, and just installed Office 2007 evaluation edition. (So I can use either or both.) Office 2007 doesn't include Document Image Writer, so I wouldn't expect anything to happen with 2003's program. But I can no longer print to it. I can view previously printed MDIs with no problem, but I can't create new ones. I can't even print the default test page. It just says "Test page failed to print. Would you like to view the print troubleshooter for assistance?"
Also, when I attempt to bring up "Printing Preferences" from the printer setup, which I believe is where the default folder setting is, it doesn't bring up the dialog box. Looks like maybe its trying to, but nothing ever happens.
