Buttons

[David McFarlane]

Gilis,

Standard reminder:  1) I do not work for PST.  2) PST's trained staff 
really does like to take any and all questions at 
http://support.pstnet.com/e%2Dprime/support/login.asp , and they 
strive to respond to all requests in 24-48 hours.  So don't be shy 
there.  3) If you do get an answer from PST Web Support, please 
extend the courtesy of posting their reply back here for the sake of others.

That said, here is my take ...

If by "buttons" you mean mouse clicks on specified areas of the 
screen (as opposed to buttons on a button box), then I think the 
conventional way to do that in E-Prime is with Slide.HitTest(), which 
you may look up in the online E-Basic Help.  Also, if you look at the 
Samples on the PST web site you may find an downloadable example of 
how to use this.
