Scrolloing within MIDI/Instrument tracks

Here is the “Problem”.

Often, whilst scrolling up an down the track list, I don’t notice that the focus is on the rhs “data” side of the screen and not over the track listing on the left. Consequently the note data within the current track “accidentally” scrolls instead of the whole screen just moving up or down.

This means that if, sometime later, I return to do some editing on that track the note data is now not in view and I have to scroll up and down within the track to find it.

The question.

Is there some way to stop this accidental scrolling until such time as I actually want to scroll in the track?
