Hi all,

I've an WinXp SP2 on my Laptop. After using it for a year, it began
that after a couple of hours, it is no longer possible to click on the
start button. A right click is still possible. Even pushing the window-
key, or ctrl-esc does not unfold the menu. After a reboot everything
is fine. It is quite annoying and in other forums and newsgroups i
did't find an answer.

Please help
