Keith et al: Are you using the latest version of the WU add-in? We
don't upload to WU here so I can't comment at first hand but I'm aware
that this issue has been around in other forums for a bit and some
seem to have achieved a fix with the latest WU add-in version. One
recent thread is:

NB AIUI you'll need to be running v5.5 or preferably v5.6 of WL. If
you're using an older WL version this won't be relevant except in the
sense that WU have I think changed the way their servers operate from
what was fully compatible with earlier WL versions.

Basically I think this is largely caused by the fact that WU write
their own add-in to interact with their own servers (ie this is part
of the overall add-in philosophy and it's not anything directly to do
with the Davis programmers). And it sounds as if a previous add-in
version wasn't 100% robust.
