This is only a problem for Mac users who use screen switching. Poser tracks the cursor even when it is on another screen. This is NOT about multiple monitors. Screen switching lets Mac users have multiple screens which can be switched with keystrokes like control right or left arrow. If I start up Poser on one screen, then switch to another, Poser still updates the cursor appearance when I move the cursor across panel boundaries. That means I might be in Safari, but Poser will notice the cursor entering the pose room view and change tthee cursor to the rotation tool symbol even though I cannot see the Poser window.

Is there some way to suppress cursor tracking and updating when Poser is not visible? I think the Mac reports window activation and deactivation when screens are switched.
