Hi, this is not really sublimes fault but I think it could be handled better. If you unmount the filesystem that sublime is running on the whole application freezes and you have to force quit. I've only used sublime on Mac OSX, but I would expect the same thing to happen on Linux or windows. It would be nice if there was some sort of error message and or option to save in a new location when this happens. Really anything other than the hangup that happens now.
--Edit: Forgot to mention sublime version.
