When I startup win xp, clicking (left or right) items in the taskbar or system tray has no effect. Pressing C-A-Delete will then allow normal clicking on the taskbar and system tray.
This behaviour may recur later, with a similar fix.
Apart from latest firefox update, no software installed immediately before the behaviour appeared, about 4 days ago, when I was holidaying in Vietnam (could that be a relevant factor??????)
My first thought, rationally or otherwise was virus/malware/??? - my school, who own this computer and insist on McAfee have, in their wisdom, somehow disallowed scan on demand, so I can't easily scan for a problem.
Maybe it's something else, but I can't see any "unusual" processes running from the task manager (to my untrained eye that is)
Thanks for any help
