Hello,
Regarding the stalling of the commandline, we already fixed something that might explain this behaviour/bug, so please check again in the next update/maintenance release (probably in a few days).
Regarding the colorFX, I couln’t reproduce anything. Do you have a showfile/example?
Regarding fixtureselection, is it possible that you are in RANGE mode instead of SLICE mode (in toolbar of e.g. fixture window). This is a global setting that the commandline will follow.
Jo
