I've been noticing something really annoying lately on my laptop. When I open an application or even command+tab to quickly access an already open app, I have to click on the window that just opened in order to make it 'on top' (if that makes sense). So if I want to quickly paste something into word from safari, or even quit an open app, I have to physically click on the app's window first before keyboard shortcuts will actually perform the intended action. It's not something that has always been the case, and I'm not quite sure when it started. Anyone else have this issue? Is there a setting I somehow have accidentally unchecked/checked?
