NIS is performing a background task

In any release I've ever used in the past, this prompt would dissapear the moment I moved the mouse. 

 

The cleanup of Windows temporary files is running as I return to an idle desktop.  Moving the mouse or running any program will not dismiss (slide away) the messsage - like before.

 

Clicking X will close the message with the task are complete message sliding in.  That message does time out after a few seconds and slides away.
