Are the mouseEnter/mouseLeave handlers in the group script or the  
image script? If they are in the group script, this doesn't sound  
like a bug (apart from the crash).

If you have backgroundBehavior turned on, messages will pass from  
object to card to background (group). So a mouseEnter message on any  
object on the card will be handled by the background script (if it  
isn't handled earlier).

Possible workarounds:

-- Turn off background behavior of the group.
-- Check "the target" in the handlers to confirm it is the right  
object generating the mouseEnter message.
-- Put the script in the image object and not the group.
