You don't need to dsable interrupts in the ISR, that happens
automatically. When the RETFIE is executed they are turned back
on by the hardware setting GIE =3D 1.

What you must do is clear any relevant interrupt flags. In your case
TMR1IF =3D 0. If you don't do this then the ISR will be re-entered
as soon as GIE =3D 1, as the uncleared TMR1IF is seen as a pending
interrupt to be dealt with.

Generally TMR1IF =3D 0 would be done at the start of the ISR but
with a short ISR and long timer period, anywhere in the ISR will
do the job
