'[Re: Strange PIC 16F84 I/O problem...]'
Thanks everybody!!! Serial resistor actually solved the problem...I know that
a latch up could occur (I had a similar problem with an opamp) but after I
turn off the power it should go away...I still do not understand
why there is permanent latchup..
Cap. is 0.1 uF and a quick calculation shows that when it is shorted it dumps
a few 100 mA for a microsecond to the PIC...which way to high...

I suggest you put some serial resistor between C and PIC as high discharge
current can cause latch-up. (As a thumb of rule, about 200-250 ohms should
