I agree -- things aren't great.  It takes a lot longer for direct 
access to open a folder than via the proxy, and since the proxy I'm 
using is on the other side of the continent from me I don't think it's 
a caching issue.

The current fix makes things work; it doesn't make them work well.  
There's still something wrong.
