Looks like a lot more switches than just PortB.3...

yes, you are correct but when I deleted them all but that one for testing, well you understand. Anyhow I am back to the original will porta serpin and the switch on portb, all seems well, BTW, about using MCLR and WDT when I set the config bits, other than the PBP manual that basically says to pull the MCLR high with a 4.7k what determines when to use it and I read here on the form PBP by default keeps clearing the watchdog, but also when should I be using that. Skimask, please don't say read the manual because page 8 says in general it should be on. I would like to know where I can find more specifics.

Thanks for your help and time Skimask

I will say read the manual...and the PIC datasheet.
PBP clears the WDT by inserting CLEARWDT instructions at strategic points in the code (i.e. whenever it can).
The watchdog timer is for code that 'runs off by itself'. If the code gets stuck in a loop that doesn't have a CLEARWDT timer command, it'll get stuck by itself doing nothing.
If you've got a WDT, after X seconds, the PIC will reset itself and at least do something.
MCLR - turn it off if you want another pin, simple as that.

LOL, I was expecting that, Thank you again for clearing that question up for me. I sure hope that by now you realize that I do read the manual and the datasheet and google etc.., maybe I don't understand what I have read, but a lot of us here are learning from scratch and not someone that says "just give me the code". again, thank you
