Drag and drop, resizing, moving open windows and highlighting with Big Sur
I am having issues with all of the above:
- When I select and drag a file it "loses it hold" before I reach the destination and it returns to its original position.
- When I go to the bottom of a corner of an open window and try to resize it it does not function or when it does it mirrors #1.
- When I try to arrange open windows on my desktop the click and hold does not work at all.
- If I am in a document and want to highlight a sentence, it may highlight the beginning but then "disconnect" and not complete the action.
This is occurring on a 2019 iMac running Big Sur 11.2.1. I have run EtreCheck with a no issue reported result. I have disconnected all peripherals, removed power cord and reconnected power cord, keyboard and mouse only with no change in behavior. Both the mouse and keyboard are wired. I switched form my wireless mouse to wired with no change in behavior. Tried trackpad with no change either.
I was reading a previous old post where this was happening with Yosemite and the suggestion was to run in safe mode. I have not done this. I did not see any commentary on results..positive or negative.
Thanks in advance for any suggestions.
