Change dock default
I'm using Mojave 10.14.2 on my iMac. With previous editions, when an app that I had not specifically put into my dock was used and then closed, it automatically disappeared from the dock. Now, the apps stay in the dock, segmented to the side, unless I go in and click on Remove from Dock.
Is there a way to change the settings so it will work like it used to?
Thanks in advance for any help.
