Switching Sequences Causes Left Mouse Button to Be Held Down
Some people have previously reported that when you switch sequences (always happens when clicking the sequence in the Timelines window), that the seqeunce tab will get dragged out of the window as if you're trying to move it elsewhere and that it's all dependent on if you move "too fast". After the most recent time that happened, I noticed that the crosshairs icon came up on my cursor and it started to marquee select in the timeline for a few seconds.
This part is new. But to stop this madness, same as before, click in an empty space in the timeline.
This issue has been going on for at least a year.
