I have noticed that the option to "Page Mode -Show Bookmark panels" in "Tools -Set Open Options" is not working as it should. Actually, as I have tried it, it is not working at all. The bookmark panel does not show up. I have tested with single files and with multiple files. But, if I go back to version .57, it works just fine.
Thought I would let you know (especially because we use this function all the time)
