Endnote X7.3 keeps getting "hung up"

There doesn’t seem to be a whole lot of rhyme or reason to it, but sometimes Endnote will really get hung up and take 10-15 seconds to whatever the task is. Sometimes this is CYWY functions, sometimes it is just within the program (without Word).  I don’t think it is the size of the library, based on hearing from others in the forum (mine is ~9k references, with 7k attachments).

Any suggestions?

too many output styles can degrade performance?

So far that seems to be working; Endnote seems to be pretty snappy so far… For some reason I had all of the output styles installed. I was able to remove all of them by using “Change Program” in Add/Remove programs.

I’ll be back if I start getting hung up again. Thank you!!

EDIT: Nope, still getting hung up occasionally. Doesn’t seem quite as often as before.  Any other ideas?

Connection and filter files should be trimmed.  In the word processor, I turn off URL links to bibliography and accept any tracked changes, if there are problems.
