Bonsoir David,
When you use Rev 2.9 feature, Rev sets the blendlevel of the
dragImage you specified to a value that makes it enough transparent
to see what you hover when dragging.
This blend level can't be specified and is set by the engine.
If you accept it, it might solve your problem because you no longer
drag a Rev object then objects on the current card receive dragEnter
and dragLeave messages you can easily handle.
If you don't accept this automated blend level, run you own and
detect where is the mouseloc.
"How to manage drag and drop #2" tutorial might help you:
This stack explores all ways to manage Drag and Drop especially with
Rev 2.9 new features:
In one Rev window, between two Rev windows, from Rev or towards Rev
with text, images, files, etc.
How to create a drag image on-the-fly, a tools palette and many other
tricks.

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.
David Epstein
Bonjour David,
Actually, 2.9 drag and drop feature is able to solve your problem if
you accept dragged object's automatic blend level.

My question about "grabEnter" has led to an interesting broader
discussion of the relative merits of grab vs mouseMove..
I would be happy to write a more complicated "mouseMove"-controlled
script, but as far as I can tell that won't solve the problem I
posed. If the user is dragging an object, whether using "grab" or
by a script reacting to "mouseMove" events, no objects beneath that
object receive a mouseEnter or mouseLeave message, because the
mouse remains within the object being dragged.
I can think of ways of amending Transcript that would solve this
problem--probably by extending the current usage of the various
messages associated with drag and drop actions. But is there any
way to do what I want with the language as it is? Capturing
"mouseMove" doesn't tell me "what control the dragged object has
just moved on top of" unless at each nudge of the mouse I compare
the mouseLoc with the rectangles of all potential target objects.
