Timeline shuffling when moving spline points

I am using mocha to rotoscope. When I go to correct spline points that have fallen off the edge during the track, often the cursor on the timeline starts shuffling as I am doing the correction, so it moves me off the frame I want to correct and starts auto-generating loads of keyframes. I then end up having to delete the extra ones and often lose the frame I was on… I’m not a regular mocha user so I’m sure it’t something simple but it’s really annoying! Can anyone help?

This sounds like you’re accidentally scrolling the mouse wheel or trackpad.

You can turn off timeline scrolling under Preferences > System > “Enable mouse timeline scrolling”
