When I move the mouse cursor sideways across the desktop, the open windows disappear to the sides of the screen. Then you have to click on the screen edge to bring them back. This has become a big annoyance and I'd like to disable this "feature". I didn't find anything in Apple Support or mouse instructions, or System Preferences. It's an iMac, 27", late 2009, macOS 10.13.6 with a wireless mouse.
Thanks for any suggestions.
Your problem seems to be that you have set three of the "Hot Corners" to show the desktop -- don't think this is what you want is it? This "Hot Corner" behavior kicks in whenever your mouse cursor on screen moves into a corner - and if it does then the behavior you have selected for that corner kicks into effect.
Suggest turning all the Hot Corners to just "-" which is the last one in the possible list.
Does that make sense? Perhaps read more about "Hot Corner" use at How to use Hot Corners on Mac | iMorehttps://www.imore.com › how-use-hot-corners-mac or at https://support.apple.com/guide/mac-help/use-hot-corners-to-start-the-screen-saver-mchlp3000/mac
Just google "hot corners on mac" to see lots more.
Good luck...
I recall turning that on but not knowing what it would do! "Hot Corners" sounds a lot like "Hot Ticket" I guess.
Thanks to all for your help.
