Edit > Preferences > Interface... and set Live Screen Drawing to Delayed.

Thanks Peter, but as I said already - we tried these methods to no avail. I think I have found the problem after examining more closely my colleagues work. Will post tomorrow if the solution works, but most likely the problem is due to too many master pages that are based on each other.
Hi A. Tz.
I seem to be having the same problem as you were having with Indesign working too slow...were you able to find out what the problem was? I can barely work in the program it's so slow....just wanted to check to see if you figured it out.
Do you have any third party plugins installed? You are probably best off posting in your own thread rather than hijacking an old one.
