Infuriating 'Marquee' Tool Cursor Causes Mouse to Disappear!

I NEVER use the marquee tool - but often edit automation point by point.

When doing this, the mouse cursor disappears and is replaced by the marquee tool - a tiny crosshair that is barely visible. Shaking, moving, clicking, or pressing a hotkey to make my cursor visible again is infuriating and a waste of time, but these seem to be the only options available...

Is it possible to replace the barely visible crosshair with a different graphic?

Or, is it possible to permanently disable the marquee tool altogether?

I thought I had discovered a workaround - using an app called 'mousecape', which enables the use of custom mouse cursors as well as editing existing cursors - but unfortunately this does not prevent the cursor from reverting to the dreaded marquee crosshair when editing automation points in Logic.

Please advise!
