Bruce,

I've used that code successfully with pGbuild, so the problem 
probably lies elsewhere. I'm not sure what else you are doing (in 
your code---like allocating data with Newhandle etc.), so it is 
difficult to assess. I'm assuming when you say QUIT that it really 
has a failure but you just don't see it. Do you have MacsBug 
installed? This will trap most of these failures and give you an idea 
where it is failing. Maybe you should turn on "array bounds checking" 
temporarily to check that possibility. Maybe you can post the code 
that builds the window. I'll be happy to take a peek and see if my 
meager skills can uncover something for you.

Brian
