Running 1.9.8.9.0.101 on a 1K Ion (2x20 wing, 1 VGA screen, 1 ELO touchscreen - single user/operator/programmer/designer/dogsbody/scapegoat)
I noticed when a lamp is selected, repeatedly selecting the color format button below the color picker in ML Controls (I had mine in the CIA) drifts the current color a bit every time you click on the button (but not within the color wheel) - found that a little odd.
The per-click changes are small - but if you're flipping back and forth a bit they add up.
