Hi

I am having a problem with the taskbar in Windows. Every now and again it
does not respond to input ie clicking on the start button, right clicking
etc. The OS is not frozen, clicking on the desktop works OK.

Eventually the taskbar begins responding again and all the previous attempts
to access the taskbar occur at the same time ie start menu
opens/closes/opens/closes etc.

I have had the task manager open when this has occured and the system does
not show any activity (CPU usage 0-1%).

Any help would be appreciated.
