I'm running Windows 7 x64; I often leave two or three Explorer windows open (Windows Explorer, not IE) when I shut my system down, and notice that when I boot it up again, one or more Explorer windows will often open without the line that holds the address bar and search window.
It's not an insoluble problem; To get a new window I right-click on the location in the folder tree on the left, choose "Open in New Window", and then close the faulty one.
But it's strange that it happens at all. And I can't find any pattern to it; it's not the same location, or drive, that this occurs with each time, and it's not even the order of processes (for instance, it's not, say, the third Explorer window that opens that opens as faulty). The majority of the time, all the Explorer windows open fine, but then I'll get a session where two or even three windows are missing their address bar. It seems completely random. And I've never seen it happen when I open a new window with Windows-E — only when a boot opens remembered active windows.
Has anyone got any thoughts on this, please?
