Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

The inputs tend to float a bit if there is no termination. Try putting a 10K resistor to ground, and see if it fixes this.
