Activity Monitor only displays the left column (the names of the processes) -- no other data appears
My browser's Activity Monitor has suddenly dropped all the data except for the left-most column.
Only the names of the processes appear, no other data. The screen is otherwise blank.
I've been through a number of restarts of both the browser and my MacBook Pro.
What is the likely cause and what has to be done to restore normal display?
Thanks.
