Windows XP + e:cue
This applies to Windows 7 and MXWendler version 4.2 and above
If you use e:cue programmer 5.2 ( and possibly other versions ) to send dmx data to MXWendler, some values drop to 0.0 every two seconds, or stay at 0.0 for two second and jump to the desired value for a short time.
e:cue sends wrong values.
e:cue supports sending up to 4 universes.
If you use different universes, the problem appears, if you use the same universe 4 times the problem disappears.
