I did try that but it seams that the move command is not threaded and  
can not handle other commands while executing.

Thanks Bernd

That was just what I needed.

Yet there is a but...

I put this script in the left polygon and I made it none-opaque:

on mouseUp
    beep
    put the mouseLoc into x

    repeat with i = 1 to number of lines of fld fAllPoints
       if x = line i of fld fAllPoints then
          put x
          exit repeat
       else
          put "M " & the mouseLoc
       end if
    end repeat

end mouseUp


The beep gives me audio feedback that I clicked the graphic

In the majority of times the Loc came out with an M in front of it  
meaning that the mouseLoc was not on the pointList

So what Rev considers ON the graphic is different from your pointlist.

Tried to replace TRUNC with ROUND in your script, with same result
