When I am in full-screen mode (Mountain Lion 10.8.2) using Logos 5.0a-SR1, the library icon does not work. When I exit full-screen it brings up my library, but when I go back to full-screen, it doesn't work. Am I missing something or is this a bug?
It's a known issue (http://community.logos.com/forums/p/60485/431988.aspx#431988)
In the mean time, you can right click on the icon and open it as a tab...
Or use [Command][L] and open it in a floating window.
Thanks to you both!
