    I am seeing the exact same problem and I can confirm that a reboot of 
Win XP helps the problem temporarily. (this is my laptop so it is restarted 
regularly) It seems something is getting cached or stuck somewhere after XP 
is up and running for a while that is causing the 30 second delay descending 
down the directory tree when using the "file-open" dialog from MS office 
applications. There is nothing on the MS lack of knowledge base and google 
hasn't been my friend on this issue. Do you have any other ideas that might 
help get this issue resolved??
