Can't resize Lightroom Classic window on my iMac

[Mitchell Z]

Lightroom Version Number

12.01

Operating System

1. macOS 12 Monterey

I'm using Lightroom Classic 12.01 on an iMac (Retina 4K, 21.5-inch, 2019), running under OS Monterey 12.6. On launching Lightroom, the window occupies almost, but not quite, the entire screen, which also shows on the right, the top right and sometimes on the bottom, the dock and the edge of the desktop or other window that is underneath. See image below.

The Lightroom window cannot be resized. If I mouse to the edge where I can see other stuff, I ought to see a resizing scroll or something other than the arrow. But I don't.
I'd like to be able to look at other files or folders while I'm in Lightroom, but to do so I now have to minimize Lightroom. Which I can only do with Command-H. When I mouse to the top left of the screen, I don't see the Red-Yellow-Green dots for the window. I don't think this can be standard for Lightroom, but I don't know. Help?! Thanks.

Shift+F once or (probably) twice. That key combination cycles through a couple of "full-screen" modes, so using it once or twice will restore to the "normal" view with the Red/Yellow/Green dots.

Thanks so much! That did it.
