Detecting mouse clicks

[David McFarlane]

ELine,

I am with Mich's suggestion 2 -- Just use a 
TextDisplay or Slide plus an ordinary Mouse input 
mask, no inline code needed.  I never understand 
why so many people immediately jump to using 
complex inline code instead of just using the 
capabilities already built in to the E-Prime objects.
