I just installed 4.5.0 and when I opened a book with E-book Viewer I no longer have the toolbar controls on the left of the page of text. All I see is the text of the page.
If I right click the tex,t I can get a ToC, but even that is different. It's a separate window.
Any idea how I can get the toolbar on the left back (it's what has the forward and back arrows, etc.)? I must have done something to hide it.
