In regards to this fix:
- MouseEntered/Exited are no longer called when you Click an object. That can be somewhat easily worked around, but I was using the previous functionality.
- If you have MouseEntered() set for mapped objects, it will trigger as you move around the map (with your mouse cursor over the map control). This is only somewhat of an annoyance in my case, but I could see it being a game breaker in others. There is also no way to work around it, as far as I can think.
