>I have a form that has a couple of clickable image controls (arrows) whose mouse pointer is set to Hand. Our tester is finding that over RDP, the clicking of either image control causes the mouse pointer to change to hourglass and stay that way until the mouse is moved or clicked again. This behavior does not happen when the app is run locally.

Have you tried to manually reset mouse pointer in the Click method? I also remember having problems with double clicking on the grid header - the mouse pointer will change to Hourglass. I think we were unable to find 100% working solution to this problem.

This is the thread Re: Grid Sorting and Mouse Pointer Thread #1413103, may be some ideas from it can help.

See also Grid takes long time when Image control used Thread #1472780 - may be relevant.
