16F181: can't wake up from sleep

That happens to you too ? Welcome to my world

OK guys... got it going. Here is the snippet of the the code around the sleep command. Works like a charm.
What I've done is I gave it a delay of 3 seconds from the closure of the switch to make sure PortB is undisturbed, then I took a snapshot of PortB (read it into a dummy variable), set up the interrupt and put the PIC to sleep. Once awoken, I read PortB again and cleared the flag.

Now here is another question... I'm also running Darrel Taylor's interrupt routine based on TMR1. I use it to flash a LED if a battery is low.
However, once the chip awakens from sleep, it would appear that this interrupt isn't working anymore (ie. no flashing).

I've noticed the same thing happens if I try to declare INTCON=00001000 at the top of the program... does this make sense?

    pause 3000
    dummyread=PortB
    intcon=%00001000
    @ sleep
    @ nop                       
    dummyread=PortB
    intcon.0=0
