Getting Out of an App:

Get to the Desktop, and then "Force Quit" this app. Or if you don't want to close it, you can get to the Smileyface and you'd be in Finder --and no longer the app.  See my User Tip: [command+tab] Use it to Access your Mac when Something is Not Responding - User Tip

Double clicking top pane/bar on any open window minimizes it into the dock. Has always worked just fine regardless of what app, file, folder or whatever it's about.

But as of a few weeks ago, Mozilla Thunderbird is refusing. Doesn't matter how or where I click, the window stays open. I don't know there should be some right-click menu popping up with a minimize offer as nothing happens when I try that either.

I have latest version of Thunderbird (128.1.0esr (64-bit)) so no update available. So, thinking of downloading and do a fresh installation, but worried that all data I have will be overwritten or something.

Anyone?

Command H will hide an App. Command Tab will show all running apps. mouse or tab through the list.
