the grabbedObject?

Eric, Richmond,

Merci.  Custom properties are indeed one of the handiest features of  
Rev.  (The grabbedObject ought to be a revProp, I think, but oh well.)

Unfortunately it appears that mouseEnter messages do not fire while an  
object is being dragged?  Using the scenario you propose (essentially  
what I wanted to do) I get no textColor change until I drop the  
object, leave the field, and then mouse back in.  Does "grab" stop  
certain messages from being passed? (Message watcher would indicate  
that it does.)

On the other hand, Richmonds solution works (mouseMove fires) but this  
is being sent constantly while the letter is being grabbed/dragged  
around, whereas it would seem simpler to set the color upon entrance  
to a new field and be done with it.
