Pic hangs on interrupt

hi frnz...

designing a code to meaure time diffrenec between two pulses ,using int0 and int1 .When int0 caused detectd zero crossing the timer starts and when int1 detects pule of zero crossing the timer stops.
Problem is that pic46k22 hangs unneccessarily and GLCD display gets distorted.
Why is that servicing interrupt routine hangs the controller????????????????
