Richard,

I'm afraid I've forgotten what little I had learned of SuperCard.

I did note that Kevin said during a recent programming conference 
that there are upgrades coming in Rev's graphics capabilities. 
Anxiously awaiting.

Along the lines of programmability of markerpoints, I would hope that 
if RR offers bezier graphics, that the handles are programmable, 
unlike the current marker points--or maybe they are, but I don't know 
how.

I have in mind applications in which the user is allowed to 
manipulate bezier handles to change the graphic shape *and* act upon 
the results. For example, the handles could be programmed to report 
the new area within the closed bezier polygon--easy to do. I am 
thinking in particular of my Manning Formula Calculator which needs 
the perimeter and area inside the bezier closed polygon in order to 
calculate flow rates in the canal.

Wish I could respond more intelligently to your comments about the 
engine's implantation of graphic reshaping. Even after a couple of 
years of use, I still find myself overwhelmed by RR's potential.

Watching the Fedder/Nadal tennis match as I write this. I feel about 
RR the way I would if I were on court against either of these two.

Don't understand how  Maria Sharapova's lost. She is soooo cute.
