Mac 14.2, Finale 25.5.0   Very frequently, when editing (particularly in Speedy) Finale will respond to a keystroke by jumping to another part of the score, sometimes

back to the beginning, sometimes to what seems to be some random spot in the score. I thought perhaps I was pressing the keys too vigorously, but this happens sometimes even with the gentlest touch. It is infuriating, frustrating, and slows me down considerably. Is anyone else experiencing this issue?  There is also what seems to me a hyper-responsiveness to the mouse, but this is a secondary problem compared to the one just mentioned. Particularly when working with a big score, this makes navigation quite challenging.
