Problem with 'action cannot be completed'

[woodlander]

I have been using UR for some years now with no problem. However an issue has now arisen which is slowing up/ preventing me accessing items as normal.

After starting UR I get the message:

"action cannot be completed because other programme is busy. Choose switch to activate the busy programme and correct the problem"

When I click Switch the Windows XP start menu pops up. If that is cleared the problem initially disappears but then the message often appears again.

This happens even if I am running just one urd file within UR. There are no other applications open within Windows other than a virus checker.

I would be grateful for advice on how I can work through steps to solve my problem,

Best wishes, John M.
