For some reason I cannot get the Book Details panel to display on the right. Either by setting
Preferences->Look & feel->User interface layout: to
Wide or by using the
Main window layout->Toggle layout between wide and narrow shortcut (Alt+Shift+L).
When I change from Narrow to Wide (or use the shortcut) the BD panel disappears from under the Book list, but doesn't appear on the right edge.
I'm 99% sure it's something I've done to settings, because it's working fine in vanilla portable.
Any suggestions on where to look for remedy.
EDIT

Sort like it's in a state of Hidden when layout is Wide and Shown when layout is Narrow.
