WOOHOO, you got it, they're gone, so you input are there, taking a beer or twelve waiting for the next incoming sparks to blow you chip.

I know I will make friends with that one
Mister E, Thanks but I am not sure I understand what you mean. If I am going to use the RB0, RB0 and RB1 as simple N.O. Pushbuttons if I power down my board there will be nothing there. If no power the PB isn't going to do anything right?
Thanks
