Something is wrong here - Movers and their position

Hey,

So this is fun........

I will position my movers using a pre-made focus palette. They go to the focus palette. I start going through Image, beam etc to get our Mac 500's cued up. Then, every once and a while I'll change Encoder pages and the Mac's, in unison will pan/tilt to a totally random position. I will recall and/or recall & re-recorded my focus palette but everyonce and a while the board will still order the macs to move to a random position. This has never happened in a "one off" position but only when the Macs are in a focus palette position. Anyone else have these problems? I have deep cleared recently.

Thanks,

-Clayton
