On the previous version I had installed (4.21), pressing space bar would only start playback in the "sequence preview," not whatever audio or video clip I had selected in the "clip preview" section. It initially annoyed me but I grew to realize how valuable it was. Having to click back to sequence preview or click on the scrubbing bar is an irritating extra step slowing me down. I thought it was the entire purpose of making the play button for the clip preview "ctrl-space." Is there a setting to change it back that I'm missing?
I can get used it, but I'm also noticing that it's created another problem. Sometimes playback gets frozen "on" and can't be paused for a few seconds when the sequence preview starts playing. Never had the issue prior to this update. And it's not a hardware issue. The only reason I have the update is because I installed it on a brand new super fast PC.
