I have strange behaviour appearing since I have been using Snow Leopard, and it manifests itself on at least three different Macs. I cannot find any references to it, but I intermittently have Finder windows that stay open (I cannot close them, either with the button, the Close Window command or the command-W key combination). If I log out and in again, I am able to close them, and I am also able to do it by force-quitting Finder (though once that managed to fail to restart the Finder at all, so I don't like doing that - I then started to just leave the "extra" windows open - I don't think I have ever ended up with more than two "stuck" windows). It doesn't happen to all windows, only some of them, and I have not yet been able to work out why they get "stuck". I run my Finder with the sidebar turned off, but sometimes turn it on temporarily using the keyboard to go to another computer (on our "network" of connected Macs at home). I tend to have several Finder windows open at once, using command double click to open additional ones. I am not sure, but I think the windows may get stuck when I command click the sidebar to open Finder windows showing details of other computers. No matter where I navigate to in the window once it is open, using the sidebar or not, I still cannot close it. When I try to close it, I can see the close button flash in the top left-hand corner of the window, but it doesn't close. The Close command on the menus is visible (not greyed-out) but also just makes the corner flash before failing to close the window.
Does anyone know how to shut the windows down without force-quitting the Finder? Has anyone else got similar behaviour? It is the way I use the Finder? Has anyone reported this? I could not find any similar mentions of this on the discussion forums or in any of the Support section of the Apple site.
