   The thing you're missing may well be a property called "blendLevel", which 
basically defines how opaque the top graphic is. Just for grins, you might 
want to try making button on the same card as your blend graphic, and give said 
button this script...

on mouseUp
  repeat with K1 = 0 to 20
    put 5 * K1 into BLevel
    set the blendLevel of graphic "Whatever its name is" to BLevel
    wait 3 ticks
  end repeat
end mouseUp

   This handler is, of course, *extremely* quick and dirty, but it should 
serve to demonstrate my point.

   Hope this helps...
