The clip speed slide jumps it's value from 1.0 to around 1.43 just by clicking with mouse button using BETA 2, I use to reach sync of parts of the video on live performance when band are not plugged with video. And became a mess to fallow the sync again.
The strange part is that do not happen using BETA 1. Made me to downgrade to reuse Beta 1 again even with the minor bugs.
