I'm new to DJGPP and interrupt handling in general.

It seems my interrupt handler is hanging (not returning). Is this 
possible? I'm using a modified version of the interrupt handler example 
from the user guide (Guide: Interrupts Overview). When I run the code as 
is, using IRQ 0 (Timer) the counter increments as it should. But when I 
change the IRQ, to 5 or 7, and manually trigger multiple interrupts, the 
counter increments exactly once. What am i missing?

Thanks,
Jason
