It sounds like the capacitance of your hand is affecting the circuit. 
Some key areas to look at.

1.    Is the clock stopping? Have you got recommended capacitors to 
ground on each leg if using a crystal. Or any at all? Is clock set to 
right mode for the crystal or resonator you are using if using such.

2.    Are all unused pins set to outputs OR set as inputs and 
connected to Vdd or ground (either via a resistor (recommended) or 
directly. A floating input pin can cause almost anything to happen. 
Enabling internal pullups where available is good enough. Setting as 
outputs (if the cct allows you to do this safely) is even better.

Report back on the above for more ideas :-)
