Trouble with VMail

I recently returned to using QNX. All is comparatively well except with
V-Mail. When I first set it up using a POP3 server it would start to
look for new msgs and then just sit churning away and not stop or allow
me to interfere. Moved to IMAP, but though I was able to download
headers I cannot retrieve any bodies of msgs. I know this is very
general as to description, but perhaps it may ring a bell with somebody.
Thx for any thoughts.

Also, I have noticed that the memory bar rarely moves at all and the
CPU is often pinned at the top end for long periods. How can I check to
see if QNX is in fact using the memory effeciently? Dave Danforth
