Another thing comes to mind : The interrupt latency.  When you disable a
Interrupt the interrupt-handler (especially the RETFIE instruction) could
re-enable it.  There is a piece of code in my book that states that you
have to _check_ if your interrupt is off.  Example states :

LOOP:
  bcf INTCON,GIE
  btfsc INTCON,GIE
  goto LOOP

Hope this is the solution to your problem ...
