Do you possibly have the T1OSC oscillator enabled?

Also, as indicated previously, it is generally "much" easier
if you first get these things running in polled I/O mode,
instead of interrupt mode. Fewer things to go wrong.

Thanks Dan,

You got it.

I did have T1OSC set and that is why I had the problem.
I did try to poll RC1 in I/O Mode but had the same problem.
Now it works !!!

Thank you very very much.

Best Regards, Fred
