New Big Sur upgrade. . . downgrade for click drag?
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.
