Katie,

Stock reminder:  1) I do not work for PST.  2) PST's trained staff 
takes 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 (although latest 
reports indicate more like 10 days) -- this is pretty much their 
substitute for proper documentation, so make full use of it.  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 ...

I can't go into full details, but here are a few hints that come to mind:

1) You will have to resort to inline code to do the Slide.HitTest.

2) I would probably use the main Slide to collect just the keyboard 
responses.  I would use "extended input" (see Appendix C of the 
User's Guide that came with E-Prime) with a Duration of 0, increased 
MaxCount, EchoClient, etc.  I would then follow the Slide with inline 
code to get the "Next" mouse click.

3) Unlike other input devices, you do not need an input mask to get 
mouse responses, see the MouseDevice topic in the online E-Basic 
Help.  And because getting the "Next" might take several mouse 
clicks, I would get the mouse clicks directly (i.e., without an input 
mask) and use Slide.HitTest in a loop in inline code following the Slide.

4) In particular, your code
     Do Until (strHit = "Image1")
     Loop
is an empty loop and will do nothing useful for you.  You need to put 
the appropriate code inside that loop.

Hope you find some help in that,
