Detecting mouse clicks

[David McFarlane]

Just a few thoughts:

- Maybe your code does not reference the correct input mask (that's 
the index number in, e.g., Task.InputMasks(1).Responses.Count -- see 
the documentation the in E-Basic Help facility).

- Maybe EP *does* detect your mouse click, it's just that your code 
does not then do anything that has a visible effect.

- 80% of the time, problems like this arise from the very design or 
structure of the program, and when I get stuck, I start to back up 
and rethink the entire design.  Early on you went down a path that 
used a lot of inline code; I would rethink that path, scrap the 
existing program, and start over with another programming design 
(perhaps along the lines that Mich & I both suggested earlier).  Most 
of the time I find that such a redesign or "refactoring" solves not 
only the immediate problem but several others as well.  Personally, I 
am not afraid to throw away the first few attempts at a program 
before I settle on a sound overall design, and even then I consider 
everything tentative.

Good luck,
