wait with messages

Thanks Scott,

Here is the workaround I did:
on openStack
  play ac "sound1.wav"
  send "mouseDoubleUp" to image "bigPlay" in 8 seconds
end openStack

in the script of image "bigPlay" I have:
on mouseDoubleUp
  play ac "sound2.wav"
end mouseDoubleUp

also in the script of image "bigPlay" I have
on mouseUp
  (do a bunch of other stuff too)
  stop playing ac "sound1.wav"
  stop playing ac "sound2.wav"
end mouseUp

What really BUGS me about LiveCode is that the documentation (example, wait 
with messages) is SO sketchy, that you cannot figure out how to use it.  I'm 
constantly wasting my time fighting something that doesn't work and then 
ending up having to do a workaround as shown above.

And as an FYI in case you ever run into this:  I imported a folder of audio 
files and LC inexplicably made my "bigPlay" image disappear - even when it 
says "visible" in the property inspector, is in the top layer and blendlevel 
is 0.  After fighting that twice, I went back and had to import each audio 
file individually.  Note that I'm using 6.1.1 (rc 4) on XP.

Anyway, thanks for the code below.  I may end up using it somewhere 
sometime.
Larry
