application exit kills shells

Hi all,
I start my application from a shell command-line.
When I exit my application, it kills the shell that its returning too.
Worse yet, since I have init respawning the shell all those subsequent
shells get killed automatically...so I get output like the following
(the >> is the prompt for my application)....

>>quit
# # # # # # # # # # # # # # # # # # # # # # # # # # # # # #

And this just continues endlessly.

Anyone have any idea why this would happen. I was thinking maybe
some signal control or terminal control or something that I do in the app.
but I can't think of anything?

Thanks,

- MikeQ
