If I try to navigate to a drive that can't immediately be navigated to (e.g. requires a password or is a network driving spinning up etc.) I get the navigation popup… but I'm unable to click it or dismiss it and it locks up the entire Explorer window. Sometimes it frees up after 30 minutes or so, sometimes it requires a reboot. This is on Windows 10 x64 anniversary (although it happened previously as well).
