Hi Andrew

My first guess would be based on just this effect, moisture on the menu key. I am sure you have seen similar effects on the computer (when you spill coffee on the keyboard?)

A complete dry out of the controller may fix the problem. Particularly as the guider input had no problem with the actual control of the scope. If not I should expect the problem to be more likely in the Gemini (ugh). Look for evidence of water here also.

I would discount the cable at the moment because the problem is relative to specific problem and I am sure you have already tried tests associated with the cable.
