Welcome to the wonderful world of PIC.

In the interrupt routine, you need to check which interrupt bit is set, 
and service that one first (then clear it), then check the another 
interrupt flag and service that one.

You could also check each bit and set a RAM flag, exit the interrupt and 
service those in your main loop.

Timing on your routines is critical, you routine can not be too long.


good luck
