Brian,

I'm not totally sure about this, but when I was testing this problem to see
what I could understand about it, I THINK I found that the "setVisible
false" is NOT what makes the control disappear in this situation, re your
test.  What I remember doing is this:

in my application, I am actually making a combination of labels & list
boxes selectivly show or not show, & that's what is not being set visible
when they should when a sound is played AFTER they're told to be visible;

 so, as a test, I rigged the program so that the code which should make one
set of controls INVISIBLE and a new set VISIBLE when a button is clicked,
had the portion that would make the current set invisible commented out ,
and when I tested it, THE CURRENT CONTROL DISAPPEARED ANYWAY on button
click; then when the "new" control became visible after the sound played,
the old control THEN showed up superimposed over it (since it wasn't set
invisible). But even though it hadn't been set invisible, it DID disappear
on the initial button click.

So my guess is that something about the initial action of the setVisible
command erases the control specified BEFORE it checks for whether or not
the parameter is true or false, and THEN the sound routine takes over,
leaving the control not there until the sound is finished playing, and THEN
the setVisible parameter is checked & the control is either made visible or
made invisible.

Does that seem at all likely to be happening?  It would explain your
result, if that is what is going on, though I'm not sure what it might say
about a fix.  I'll have to check my myrid sequence of test versions to see
if what I described doing & seeing is accurate, but I think it is.
