As always, thanks to Kovid the dev for all the hard work put into Calibre!
This is sort of a long-standing bug, but I was hoping it could be corrected; I think it's an easy fix.
I keep my Calibre library and all books on a network folder so that it can be accessed by any computer with Calibre on the network.* Frequently, when I am editing metadata, I get the following error message:
Code:
Locked file: J:\Documents\Books\author\book\book.epub
Traceback (most recent call last):

IOError: [Errno 13] Permission denied: u'J:\\Documents\\Books\\author\\book\\book.epub'
After a minute or so, if I try again (i.e., click OK or next in the metadata editor), it'll process just fine. Presumably something Calibre is doing is locking the file and preventing changes, but-whatever that is-it stops after a minute. It's not unusable, but it does slow things down.
* This error appears even if no other network device is accessing the library. In other words, everything else can be completely powered down, but the files are still locked, so I am pretty sure it's Calibre doing the locking/unlocking
