PIC16F87 pins seem to be getting crossed over

Hi,

Try a smaller pullup resistor, something like 4.7K. 100K pullup resistors might be too much. I hope this helps.

I dont think the pullup resistor is the problem. I want a fairly weak one to make it easy to ground. 100K should be more than enough to pull up any pin on a PIC. Ive used them many times before without a problem and there are 3 others on the same circuit working fine.
