Hi Kenward,
Thanks for noticing this!  It is somewhat rationalizable, because the  
"savepos" command (save position) is executed after each set of panel  
commands.  If there isn't a "wait" at the end, the position is will  
be saved prematurely and not reflect all panel commands.  However,  
you are right, it should be smarter and automatically incorporate a  
"wait" instead of putting the onus on the demo creator.

We will file this as a bug.  In the meanwhile, using "wait" after the  
panel commands is the way to go.  I never noticed this issue, because  
to make a demo I first created a single script (chock full of "wait"  
commands) and then broke it up into panels.

I would be interested to see how your demo turns out!  Please don't  
hesitate to contact us if any other issues arise.
Best,
Elaine
