XP hides "infrequently used" taskbar icons.  Try displaying all your icons
and see if they reappear.

I've been running this combination for yonks, currently under XP Home
SP2. In the past few days they've both disappeared from the task bar
(bottom right). TaskInfo tells me they're running, and they are, but I
can only open SETI Driver after a reboot. When I minimise him, his
icon's gone!

Any thoughts?
