I did put the update up.
CTRL+Click=right click, I didn't know that was a thing
I always use a 2 finger click on OS X for right click.
I think I have come to the conclusion something went wrong in my El Capitan update and never got straightened out since.
I see they are still selling 4GB Macs, so it has to work there. They couldn't sell the way this is working.
I did some browsing around and see some others that have had this happen. So far none of the hopeful cures seem to do it.. I think need to blow this OS away and start with a clean install.
