Mitch, I don't think that's likely to be the problem, if it were, all the 7081s and 7071s would have a huge problem, but they don't, just this one ...

The part dissipates a fair amount of power and the bias current, although small, does show significant change with temperature. This change multiplied by the 1 megohm input resistor may be responsible for some drift.
