My company has been using GW messenger for about 6 months or so now.
I was
enjoying quite a bit until it stopped working.

The exact issue is when I reply to a message. My wifi connection
stops
dead in it's tracks. It shows connected but stops passing traffic.
I've
confirmed this issue on several different networks and 2 computers.
Both
are win xp sp1a (thats service pack 1 without microsoft's java vm).
One
was a new laptop that came with sp1a and the other was an older
machine
that was updated to sp1a.

Any ideas on how to resolve this issue?
