I have problems with Finder freezing when a Finder window is focused on a no-longer-available network share. Here's a typical scenario: - at home, I browse my shared iMac on my network via Finder on my MacBook - I sleep my MacBook, and take it with me to work, where I connect to my workplace's Wi-fi ; obviously, the iMac shares are no longer available - when I go into Finder, it freezes up... I guess because it's still looking for the mounted shares? I then have to force-quit Finder; when I do that, Finder won't relaunch itself (I get an error with code 10810). If I just leave the system alone for a while, it eventually allows me to launch the Finder again. Any advice?
