I installed Joomla 1.7 with CB 1.7, GroupJive 2.4RC2, Kunena 1.7 and uddeIM. Now that I finally got the website up and running, nobody can use the arrow keys (up,down,left,right) on the Frontend e.g. Forum, PM or Groupjive. It works fine on the backend. I hope you can help me to get this solved and I would appreciate any suggestion.

Thank you in advance.
