The rotating beachball is a "wait cursor." It is not at all necessarily a sign that there is a problem. It comes up whenever you have to wait a pre-determined amount of time before the requested function will be finished. So, if you are performing several actions at the same time, and they will take some time to complete, it is completely normal for the rotating beachball to show up. ___________________________________________ Randy B.
