OS? Version of ID, including patch level?
Windows 7, InDesign CS5.5, version 18.104.22.1683
Unfortunately windows doesn't give us any sort of report that helps diaganose these problems.
Is it all files, just one or two, only new ones, or only old ones?
If you create a new user and log in with that, does it work better?
Try these solutions.
2. Delete the SING component. ( http://helpx.adobe.com/indesign/kb/hang-freeze-open-create-file.html )
3. Check the user permissions and network / Domain policies (if applicable )
I have done some more investigation.
All of the files I work with are years old, and created in older versions of InDesign.
I have tried resetting the preferences, I have tried exporting as IDML and reopening. Neither of these worked.
I have located what seems to be the source of the freezing, I have sections in the bottom of the file: 4 appendices and an index, and when I delete these sections the freezing ceases completely. When I try to edit the masters for these sections it freezes again. I think there must be something wrong with the masters, but I do not know what it is.
Are there any known issues with editing documents from previous versions of InDesign that I should be aware of? Or any known settings for these masters I should look into changing to fix this issue with these masters? I would prefer to not delete them and try to recreate them.
You might want to try turning off Live Preflight. It may be checking the integiry of the index entries every time you do anything.
I'd also try exporting to .inx (or .idml for CS5 and newer files) from the original versions and opening those.
Did you ever get an answer?
I'm on an Apple at the Univerity and I don't know much about system and certainly can't change anything or install anything.
How do I restart it.
