I've been looking for answer to this also. I'm not sure if this is a good answer, but I think this may simply be a sign that the computer needs to be restarted. Reading what the previous poster said about the link being passed off to the OS is pretty good sign that this OS is the problem. Even an OS as reliable as XP should be restarted at least once a day. That has been my experience anyway. But I believe I have had other experiences, such as with Live Messenger that seemed to more persistent than a simple restart problem with OS, so take it for what it's worth.
