I'm having a few problems with my dock. Whenever I use office (yes, I use Microsoft office. I got a deal that made it cheaper than iWork, and it seemed like it'd be easier compatibility-wise) I seem to manage to crash the dock.

Usually when I am moving between spaces, I find the dock crashes. Any apps I have minimised in there leap back to their original spaces, and the thing re-sets itself. This isn't a huge problem, but it is mighty annoying, and it only seems to happen when I am using office.

Short of buying new software, any easy fixes to try for this?

I am using 10.5.6 on a mac mini 2GHz Core2duo.
