Hello Sean,

Sean>>Just curious on any reason why this happens with the 12F629 chips<<

Yes, you are correct... The 675's do the same thing. They run on low voltage, and extremely little current. You have to tie your leg to ground, so that the chip will not run off of that pins. Or you may get a chip with a mind of its own. <g>. Twi-Light zone?

I discovered it, when my chip would not reset when I pulled the VCC. Though I still had 5V on another pin, the chip never reset itself. <g>.

I think you will find it will happen on a quite a few chips. My guess would be most of them, depending on what pins are used for etc.
