Are these windows in maximized state? You might want to hold the Option key on the green button to see if they are.

The windows have various controls that can be activated depending on where your cursor is.

1. If the menubar is visible (with Apple menu, Application Name, File Edit menus on top), your red yellow and green controls on windows need to be visible for full control of the windows.
2. If the red, yellow and green controls are not visible, drag the center title bar as far to the right as you can.
3. Once the controls are visible, holding the Option key while clicking on the green control can maximize the window or shrink it to the last adjusted position.
4. clicking on the yellow control minimizes the window to the translucent toolbar, known as the Dock.
5. clicking on the red control closes the window, but not the application.
6. If the menubar is invisible, you an click the Escape key to make the menubar visible again, and when you click on the green control without the Option key, will hide the menubar again.
7. If you can hover the cursor over the edge of given windows, the pointer will change to two joined opposite arrows indicating the window can be resized when you click on the mouse button.

Which of these steps is not behaving the way it should? What program do you have open that is having trouble?

I upgraded a Mid2014 MBP from High Sierra to Big Sur 11.7.2 a few months ago. Everything has been working fine until the recent update to Big Sur 11.7.3 where the mouse cursor disappears when moving it to a vertical edge of a window (every window) or the vertical scroll bar. Its been driving me crazy because it is no longer intuitive to grab the vertical edge/scroll bar for resizing, etc. Regardless I was able to go to the Accessibly options and change something so at least the mouse pointer is no longer disappearing. Seems to be ok now. I appreciate your post.

Nothing free. I would recommend seeking out http://www.apple.com/usergroups

Many offer tutorials and computer clinics.

Strange, I don't recall this being a problem, but then again I moved from Mojave to Catalina, to Monterey. Did not spent much time with Big Sur. I wonder if it has something to do with the latest update. I'll ask around.

Step 7 is the issue. Programs open: Safari, Mail, Calendar, etc. All that I use

Same issue for me. On every window regardless of state. As the mouse selection cursor moves to a vertical edge, it disappears as the pointer changes. It was noticeable immediately after the update.

Sounds like I should upgrade to Monterey (last update my MacBook Air will support. What do you suggest?
