Safe Exam Can be navigated forward and backward using ALt + mouse scroll.
We use SEB with Moodle. One of the way of using such navigation is to list all needed sites in own user profile description field before exam, and then go to profile (profile link is always visible during quiz), then to any needed site, and then return to exam with alt+scroll.
As i think the solution is to disable any access to sites, not listed in seb.ini. Or if it's alredy done, it is done with errors, because sites opens in new windows
