Event operations sliders stopped working

[musicman691]

Had a weird one happen yesterday. I've been reworking/remixing some Beatles covers that I've done in PT 11.3.1/11.3.2 to bring them up to snuff. Trying to make some edits to velocity and transposition using the event operations window and it's sliders which is something I've been doing for ages with no problem.


All of a sudden they stopped working. The slider wouldn't move when I grabbed it with the mouse. I could enter a value in the parameter space and said slider would move. If I clicked to drag the slider it would go to a center position and wouldn't move by clicking & dragging. Save the session and quit PT 2020.12. Restart PT and the session - same things happened. Opened another session and that was fine. Late in the day and decided to hang it up.


Come back this morning and all was fine. I wonder what could have happened? Session corruption or did I hit some weird key combo to cause what happened?
