When using the eyeglass icon to view topics in my project, I
used to right-click the mouse and select Back to navigate between
various links. Since IE 7 was installed on my computer, when I am
in that view and right-click the mouse, nothing happens. Any
I couldn't say why RoboHelp is behaving this way for you, I
have IE 7 (using RH X5) and can still right-click and choose Back.
You should also be able to just hit the Backspace key to navigate
backwards as well.
