Mission Control - App Loses Focus
I've had a frustration with Mission Control for about a year or two now. I use a hot corner to call up Mission Control to switch apps. Often (if not always) the app I click appears for a split second then another app will steal focus. There seems to be no rhyme or reason to what is a superior or inferior app in this situation. However the Finder is almost always inferior (loses focus every time selected in MC) and Safari seems to always be superior (never loses focus when selected in MC). This has been discussed at this site: https://apple.stackexchange.com/questions/257047/macos-sierra-lost-focus-finder-when-using-mission-controls but this is happening to me on High Sierra as well. I also don't like the work around the linked discussion suggests (forcing Finder to use only one desktop).
Does the more tech savvy MGG community have a better idea of what may be happening here?
