Whenever a prompt pops up in Excel it's not selected, meaning tab, arrow or enter keys don't work within the prompt unless I manually click on the prompt window to select it.
A good example is "Unhide Sheets." When I use the menu or key commands to unhide sheets, the prompt listing hidden sheets pops up. But I can't arrow down to the individual sheet I want to unhide because the prompt window is not selected (highlighted). I have to manually click on the prompt to select it and only then can I navigate or hit enter.
This glitch happens for every popup/prompt in Excel and only began to occur about a week ago. How do I fix this?
