Oh, that solves the problem! Is this (technically) the only way to do it? Are windows without such a task bar entry never accessible via Alt+Tab? Why is FARR blinking very shortly when pressing Alt+Tab if the option is not activated?
It would be nice if the back/forward keys on my mouse would work in the HTML viewer. Their purpose is to quickly navigate back and forth without using the usual buttons near the browser's adress bar. In FF and IE the buttons work by default but in the embedded view they do not. Perhaps these events are not forwarded?
