The booking page for any travel involving the new tasman/pacific product options does not load properly for me. When I select dates that are before 17 November it works fine. From 17 November I get a blank section where normally the flights would display. At the bottom of the screen it asks me to select flights. How can I?

Edited to add - I get the same problem whether entering through main page, through multicity or the blackboard specials. The latter is particularly vile as it displays a box at the bottom of page to enter origin, destination and dates but will not allow anything to be entered for origin or destination.
