If I'm using Scheduler to run code that needs to run at a tricky time 
(it's invoked in response to a GS/OS notification proc), how can I 
safely display a dialog box to ask the user a question? I'm trying to 
figure out how to deal with a situation where something needs to be 
confirmed to prevent an accidental loss of data under this circumstance.

Right now, my Scheduler task is locking the GS up good and solid when I 
try to do my UI. I've tried an old fashioned Dialog Manager dialog box 
and an AlertWindow both, and both lock up.

I've tried just calling GetNextEvent to see if that's hanging things, 
and it's not the culprit.

Any thoughts?
