I have installed Watchtower Library as described in the "Tips & Tricks" for the 2005 Edition. Issues with this version are essentially the same as the 2005 Edition. Each section will need to have its windows re-sized the first time you lauch the program. They may not visibly re-size, or the resulting image may look all messed up, but if you exit WTLIB and re-launch it you will find that they have re-sized and are now functional. You will need to do the same for the "Volumes" section as well. First re-size the window so that the selection window is fully visible. Then exit WTLIB and re-launch. Return to "Volumes" and select an article. The first time you select an article it will not appear in the window below. Exit WTLIB and re-launch. Return to Volumes and select the same article. It will now appear appropriately and so will any other article you select.
One more issue which may or may not be new...when you go to "Preferences" in the menubar and try to adjust the settings such as display font, etc. the program seems to freeze up at some point. Exiting and re-launching seems to solve the issue. Just stick the the default settings.
