         I started on a potentially commercial project that requires this 
and got stalled by the same thing.  A calling program( language unknown ) 
is required to pass a pointer to a buffer that it provides to receive an 
error message.  Sometimes it works; sometimes it doesn't and says "A 
machine exception occurred ...".  I was wondering if this could be an issue 
with the page being swapped out at the time but this is not an interrupt 
service routine.  By the way, the program I tested my DLL with is written 
in Euphoria.

         Rob, could you come up with an example of this that works?

                 Thanks,

                 Bob
