Word Freezing Up

[SCR]

My Microsoft Word is freezing up only when I go to copy something into it. I
can do all other funtions accept copy.

I have reset my computer to an earlier date and it worked ok. The I came
back to use Word a few hours later and now I am having the same problem
again.

Should I delete Word out out and reinstall it or is there a simple fix for
this problem?

Any help would be greatly appreciated.
