what to do with the other half of the opamp?

[saxtim]

When you've got a circuit with a dual opamp used as a single (for example the orange squeezer) what do you do witht the second half of the opamp?

I've got pin 4 to ground, pin 8 to the power supply, 1 is the output and 2/3 are inputs.  That leaves 5,6 and 7.  In the PCB I designed for the orange squeezer I simply connected these 3 pins together.  I now wonder after some suggested it in my orange squeezer distortion thread if these pins should also be tied to gound?

So what exactly should I do with them? connect them all together (5,6,7)and then to ground, or some variation on that?

thanks
