This morning, after I cancelled a Send/Receive that Versamail was doing, I got a "Stopping..." progress bar that took WAY too long to complete.

Also, while sending an email with a 600k attachment, I hit "Cancel" about 1/4 way through the send, and got the "Stopping..." bar again. Turns out that Versamail had actually sent the entire message anyways (while I was waiting on the "Stopping" thing to go away. I couldn't even Cancel out of the "stopping" bar.
