I am running my etc client off of my Microsoft Surface and I am attempting to calibrate my scrollers from it because it's easy to walk around and look at individual scrollers from the stage. My problem is in the Moving Light controls, I am able to go to my last frame (16) set it with the wheel but then I'm not able to scroll up to the top to hit the calibrate button. Is there a calibrate hot key? Also is there anyway to fix this problem, or has anyone else run into this before. It has happened while our Nomad PC was setup in primary mode, but does not occur on our actual ION.
