Database errors.

[Peter Hamilton-Scott]

I recently had to remove the Dm calls in my app and use preferences 
instead. When I was using the Dm calls things would work well but the 
moment I try a hotsync or launch another app, I always get a fatal 
reset. I had my DBOpenRef (?) variable in the same source as my 
PilotMain and I used extern references to it in other source files. I 
think I must have spooked the OS using a global variable as I think the 
launch of the other app might have fooled the OS into looking for 
something that was no longer there - just a hunch.

If I want to use a global variable for my database reference then what 
should I do to ensure the fatal reset does not occur. As I say, the 
problem disappeared once I removed all the Dm calls. I was toying with 
the idea of opening and closing the database around every Dm call I want 
to use, but is that inefficient? If nothing else, it makes for ugly 
code. I'm trying to work out what to inbetween launch codes.

Any ideas?
