Splitting a Track Scrolls Away

Greetings! I’m new at using Cubase so I’m climbing the learning curve while trying to actually get some things done. (I used MIDI sequencing almost 30 years ago, so not totally starting from scratch.) So sorry if this is a basic question.

Whenever I use the Split tool to split a MIDI track in the Project Editor pane, Cubase is automatically scrolling to someplace else and I have to scroll back to continue working. I almost always put the playhead where I want to put the split, so it’s not jumping to the playhead. The note editor scrolling is linked so they are both at the same spot when I do this, so it’s not jumping to there either.

How do I make Cubase stop doing this?
