Wow .. windows.h! No doubt I'll find all sorts of goodies in there! Thanks for the responses. Just in case you are curious, in my game the mouse is normally active. Holding down the right mouse button goes into "move mode" and controls the entity's pan. Releasing the right mouse button changes back to mouse mode. The problem was that, after exiting move mode, my mouse pointer needs to get re-centered. Hopefully your advice will solve this issue. I think that those controls are somewhat like World of Warcraft, but it's been too long for me to remember.

Thanks!
