using Draftsight pro 2021 SP2. Has anyone been experiencing random changes in the draftsight environment?

(1) My osnap settings get cleared out occasionally, not turned off, de-selected in the osnap settings.

(2) Lineweight display turns itself off regularly.

(3) Dimension in paper space has a mind of its own, sometimes briefly selecting the actual scale size as the dimension, then switching to the proper dimension a second later. Eg dimension an edge =4" (screen size) second later....flop 96" (desired size)

(4) The mouse fails to recognize snap handles frequently.
