No Help needed here, but thought I'd just post this solution in case anyone else has the same problem I did. There seems to be an issue with the SetPoint software that prevents the 'Forward' and 'Back' buttons from working in any browser other than Explorer. Logitech hasn't yet released a software update that addresses the issue, so until then I found the best method to fix it, is to open the settings configuator, and change them to Keystroke assingments. All internet browsers recognize alt+rightarrow on the keyboard to be forward and alt+leftarrow to be back, enter those (respectively) in the keystroke assignments to control page changing in all broswers. Doing the above has saved me from a massive headache calling tech support to figure out why my $60 dollar mouse isn't doing what it's supposed to. I hope it helps anyone else having the problem.
