I tried working a song in Studio One 3.2 that I'd started in 3.1. When I added some new VST tracks tonight, various tracks started moving randomly all over the place. When I try to move a track, it refuses to move or moves somewhere else. When I try packing the tracks in folders, they will randomly jump around in a continuous animation. I tried copying the midi into a new file and had the same trouble there. Now my tracks are completely disorganized and I can hardly keep track of what I'm doing. It's the craziest thing. Does anyone have any ideas?
This is on a MacBook Pro, 16GB, running 10.10.5.
