There were a couple of threads on this, detecting only the actual visible graphic instead of its bounding rect.

I remember suggesting using the mouseColor function with the mouseMove message, which probably works,, but there were more clever handlers offered, that took another tack using deeper attributes of LC. I cannot remember who or how. But someone will chime in...
