Hi all, first time poster here, we're having a bit of trouble at work with one of our publications taking roughly 2-4 seconds to apply a style guide and/or undo. It's very temperamental as one day it isn't so bad, others it's unworkable. We've tried the same machine, same word doc placed into a new indd and that is fine. Is the document corrupt or has anyone got any other clues? We're all running hi end macs and rebooting or using a different machine doesn't produce any better results. Thanks in advance.
