This behavior changes everytime there is a new update: automatic opening of the launch-on library when clicking on the bibdesk icon in the dock. Would it be so complicated to put it as an option in the preferences? just next to "Application Launch... Open file...."?
I don't understand. What changes every time? AFAIK nothing changes every time. At most there have been some bug fixes in one or two releases, but those are, as it says, bug fixes. And bug fixes are not changed unless they introduce another bug or are not correct.
