We have deployed several Thin-Clients that connect to Virtual machines
and on those machines there is a problem when going to MOSS pages that
contain any dropdown menus. The problem is that the entire page
refreshes instead of just the dropdown being displayed. for example,
if I hover over a link in a document library, instead of the link
being highlighted and the arrow appearing on the right, the whole page
refeshes.

This doesn't happen with Firefox so I'm guessing it has something to
do with how javascript is bieng handled.
