just being curious, i never use the notation window unless i'm fixing a bum midi note played in on the midi keyboard.

however, i loaded up an old midi file and the cursor moved fine in the notation window on a midi piano track.

on a recording with realtracks the cursor moved perfectly in the audio edit window and the main tracks window behind it.

my music pc is hardly cutting edge - 8 meg RAM and an old 4 core 3.4 ghz AMD processor. basic video card and an old soundblaster audigy2 ZX platinum sound card.

i do get jumpy cursors if the pc is deciding on its own to initiate heavy hard disc activity such as a virus scan - i see the disc drive light flashing - but even then most of the time i get a smooth cursor movement and a flashing red light at the same time.

I have RB 2019 build 3 so if the OP wants to upgrade maybe he could try it. seems to me it might be an individual pc issue - not a general problem with RB.
