When you are sending a decimal value, ie 0.5/.5 seconds, for a Prewait time (qlabfb: Increase Prewait or qlabfb: Decrease Prewait) the OSC message that is sent is "/cue/selected/preWait/+ 0"
The decimal value is ignored and a 0 value is sent causing the command to fail.
If i send 1.5 then it sends "/cue/selected/preWait/+ 1"
All of the time +/- actions currently send the 'seconds' as an integer, while QLab allows decimal/float arguments. I should be able to look into this over the next couple of days.

Decrease Prewait does the same thing.
