I would hate to bring this up but since it was mentioned that the design should still work. Well the screen does. However, the categories function does not work. Since it points to the new design and therefore does not have that in place. Have not tried to search as of yet. however, it might also be pointing to the new area as well. If you are going to leave up the old design with all of its functions then the programmers should have tested this out before making a new design so while they get to test the new site live. (Which is usually a bad idea) They should have made sure that the old design functioned as it did before the change.
Just my two cents.
