Losing focus on active window

Hello erickgrau,

It sounds as though you're having issues with applications becoming unresponsive or app windows are closing unexpectedly. If so, the steps listed below can be helpful in reaching a resolution. You can also find these steps outlined in the following article.

• "If an app doesn’t quit as expected, or it’s unresponsive, you can force quit the app (you may lose unsaved changes). Choose Apple menu  > Force Quit, select the app in the dialog that appears, then click Force Quit.
• If the app quit, reopen it by clicking Reopen in the dialog that appears.
• Restart your Mac by choosing Apple menu > Restart.
• Make sure the app is compatible with your version of macOS.
• Open another file in the app. There may be a problem with the original file.
• Check for updates to your software.
• Disconnect any peripheral devices you just connected (for example, a printer). They may not be compatible with your version of macOS.
• Uninstall any app plug-ins or enhancements from other manufacturers.
• If you recently updated the app or macOS, a plug-in or enhancement you installed may no longer be compatible.
• Diagnose problems with your Mac to learn whether hardware you installed, such as additional memory, is incompatible, improperly installed, or defective."
