Is there an easy way to have a cursor change when it is in a specific window? Up until now I have been using window regions and PtnInRgn() to determine which cursor to display. That means I have to add and subtract from the regions as various windows appear, disappear, and move around. And now I am having a strange problem where I go to move a window, and the cursor changes to the wrong thing as the window is being moved. Somewhere my window region calculation is getting screwed up.

>Take a look at the kEventWindowCursorChange event in CarbonEvents.h (available in Mac OS X and >CarbonLib 1.5 and later). I would say this would be the preferred method to use.

In Carbon.h it is not clear: By responding to that message it seems like you could change the cursor over a particular window--but if you want it to change back to the arrow when the user leaves the window, do you have to catch that message on *all* your other windows and set it back?
