Comment 4 for bug 1669497

Thanks for the smart fix.

The problem is absolutely a Windows issue. It's not as bad with a removable device that's gone, but the unchangeable timeouts on Windows networking are just stupid. In particular, when a machine sharing resources isn't there at all (the DNS name might not even resolve), there should be a much quicker timeout than the nearly 30 seconds that is the default.

My problem came from storing backups on a VM that doesn't always run, and I recently opened a file from it to compare to the live Calibre version.
