I have NIS2009 (build 16.5.0.135) installed on 2 laptops-one running xp service pack 3 and the other vista 64 SP1.
Recently having updated to Internet explorer 8 on BOTH machines the one-click support no longer works and just freezes.
It cant be a faulty installation as both laptops experience the exact same problem.
I just find it hard to believe that with IE8 being available for many months(i put it off to upgrade) Symantec have not patched out this incompatability by now.
