Hi Guys,
       Me bad. Jinx and others I apologize. Please disregard my  
previous ravings. They were based on bad assumptions about what I was  
observing.

       I had an LED connected to GP1 as described, and it was  
flickering, I took this to mean that TMR0 was activating the  
interrupt, even though I had its T0IE cleared.  A quick calculation  
showed me that even with the full prescaler divide by (256) the LED  
would still be flashing at 1000s of Hz. This would of course look  
like a solid on, and not a flicker. I was able to get a scope on GP1  
and there is no sign of any signal in the 1000s of Hz range.

      Now to track down the real cause of the flickering after  
getting some sleep.

Thanks again for all your time,
Heinz
