New Big Sur upgrade. . . downgrade for click drag? When I try to move a window on my MacBook Air (press down with thumb on trackpad and use forefinger to move cursor &amp; whatever object I grabbed) it takes 2 to 5 TIMES(!) for the cursor to actually take hold of the window and move it.  It appears there is NO correlation to exactly where on the upper pane margin I grab.  For weeks now I can't figure out where the &quot;sweet spot&quot; is!   It used to be you could place the cursor just about anywhere up there and it grabbed and moved. This is REALLY frustrating.
Wishing I had not upgraded because there is no apparent increase in the OS operation capability that I notice at all.

Finally too frustrated to wait further I relented and called Apple.  Apparently this has been a problem in their beta issue of the OS-- 11.1.  Person I spoke with said he experienced it personally but since the latest BETA FOR 11.2 has come out to developers it is gone.   I just need to wait till Apple bumps out their 11.2 OS version.
