System: PC with AMD64 CPU, Windows XP Pro v2002 w/SP3 & updated patches.
New install of NIS2010, no previous Anti-Virus installed.
Main NIS window opens fine and works. Click on "history", that interface comes up. Select a different filter at the "show" box and that box hangs (not responding).
Very frustrating considering I just made the purchase and it's not helping me.
