Detecting a "grabEnter"?

[dfepstein at comcast.net]

Bonjour Eric,
Your suggestion is intriguing but I haven't understood it.  What is an "automatic blend level"?  If by script I set the dragged object's blendLevel to 50, I still do not detect a mouseEnter when it's dragged over another object.
Many thanks.
