Agenda Class Timetabling

User reported on the social sciences instance of Agenda that if you click on print timetable view, all that happens is that the view changes to list view. After some experimentation I noticed that if i click on timetable view, then click on Print Timetable view, the printable view appears in a new tab and the original tab goes to list view. If I then click on timetable view again and click on Print Timetable view again (with the second tab still there), then the second tab is updated but focus doesn't go there, so all I see is that the first tab goes from timetable view to list view. This is fairly conventional browser behaviour for dependent windows (usually popups).
Emailed user to get confirmation that's the problem. If so, I'll see what if anything I'm able to do to change the behaviour. It may not be necessary if she knows to just click on the second tab.
