Hi,
Did anyone solve this issue?
A few years ago, I've wrote a small app that uses Indesign on XP. All these years it worked great. Now, we have migrated to windows 7 and the problems start. I've tried running both Indesign as my own app as administrator without any improvement.
Why are these problems happening in Windows 7?
Kind regards
John
