sudddenly encountered a wierd little problem:
the little autohide arrow has gone from the notification area on my taskbar leaving everything on view. i have tried checking and rechecking the feature in the properties [even rebooting inbetween] but to no avail.

to make it even stranger it is still present on the taskbar of the other users on this machine.
how do i get it back on my user identity??
