I have had similar experiences with my T40.  My mouse would jump around 
and click at random times, and my Sony Clie would only sync when it felt 
like it.  Sometimes devices wouldn't register at all.  All when plugged 
into the port replicator.  Everything works fine when plugged directly 
into the T40.  I was usually able to fix the not connecting at all by 
reseating the T40 in the port replicator, but I could never fix the 
flakiness.  I just use the ports on the T40 directly now.  Maybe IBM 
would replace the port replicator if you tried though.  If they do, let 
me know.  I might try myself.
