Can't you simply declare an  internal flag when the instance of the 
xtra is inited and check on an open database command?  If it fails, 
abort without crashing.  This might make V easier to learn and 
therefore get you new paying customers.

I do.  I don't understand what you are getting at.  I have to enter 
my commands in the message window to test my code.  I can't run the 
app from scratch all the time.

Nope.  Still crashes Director MX on Mac OS X.  I had it on all yesterday.
