Yes. They are set to digital I/O (I think so anyway)

Yes, PORTA,3 is input only. Thanks for pointing it out...my mistake. My concern is more with PORTA,4 and PORTB,5.
PORTB,5 and PORTA,4 give me the same behaviour. 0.6 V = logic high when I expect 5 V
PORTC,6 however gives me 5 V for logic high.
The pins are connected to a multimeter through a 1k resistor.
Thanks for your interest.
