Hi Alan,

> I need a crash course in mouse programming in Euphoria.

Yeah! I'm dealing with the same problem.David Cuny post a tutorial
about the subject...if you want it,drop me a line and I will send it
to you.Maybe together we'll be able to solve the problem!!

I wrote a little crappy program wich shows you how to work with the
mouse in text mode and how to create buttons.It's in the user's
contribution web page...give it a try and tell me what you think
about it :)
 It checks buttons you pressed,the current position of the
pointer,the position where you pressed either left&right
buttons and something else that I don't remember right now...play
with it!

I had the same problem when I started to program the mouse!In text-
mode it seems that you have to 'scale' the screen coordinates by
dividing the X & Y coordinates by 8 (I still don't know why!!!)I'm not
quite sure but I think that it's due to some peculiarity of the Dos
system.

I've never programed before in graphical mode so I think that I
can't help you with that matter:(
...but some day I will get started!
