I actually noticed the issue with Pidgin being the only connected 
client, but the issue persisted with or without another client connected.

I can't say whether or not this used to happen in previous versions of 
Pidgin since I used to use MSN so infrequently, but now that it's the 
_only_ method of IM at my workplace, it's much more prevalent.

The official client seems to catch all incoming messages just fine. I 
also noticed that sometimes it'll pick up the messages that I send from 
Pidgin, while other times it will not.

As a side-note, using the MSN protocol that is built into Bittlebee 
(http://bittlebee.org/) seems to work as expected thus far, though that 
only equates to a few hours today.
