Editing Author Causes Zotero to Hang
                    Hi folks,
When I try to edit an author's name (either in an existing entry, or when creating a new entry), Zotero hangs indefinitely. I cannot click out of the author name to anything else in the program. This doesn't happen when I try to edit anything about an entry other than the author.
Any ideas what's going on here?
Thanks
