Slow performance on office 2003 in windows vista
 

I'm currently using Windows Vista Home Premium as my operating system. I'm
having problem using microsoft office 2003 when it's connected to a network.
For example, It's very slow when I want to set print area, choose a font from
the toolbar, etc. However when I disconnect my laptop from the network, its
performance is back like usual. I'm having the same problem with my PC using
Windows Vista Starter. I really appreciate if someone could help me. Thanks
in advance.

I hope I didn't post in a wrong group.
