Any time I accidently try to access (ie click on) a network resource that is unavailable, that window of file explorer becomes unusable until its internal timeout meter is reached. I can GO to other directories and drives but they will not show anything in them (refresh) until the network search bar at the top has timed out. This is amateur hour peoples.. the process that is handling the network connection should be separate and asynchronous to file explorer and the file explorer window should be free to MULTITASK to other things while waiting on the network connection.
