First, let me say thanx to all the people who responded.  You all told me the
same thing.  That i needed to lock my CODE resource.  Guess what? It already
is locked...  but that made me try something else.

Here is the real problem that i found.  If i put in a little while not button
loop in below where i install the VBL, the program works!  I wait and sure
enough 3 seconds later (i set vblcount to 180) it beeps.  Then i hit the
button and the program exits.  No loop, no go on the program. It dies and
I get and call to MacsBug with a DeQueue error.  What's that?

Anyway, why would the machine crash if the installing program exits before the
VBL task comes up to go? I tried allocating my VBLTask record as a handle
and locking it in case the fact that it got disposed of was the problem, but
this didn't help.

Your help is graciously requested,
