Sorry if this needs to go into the commercial program heading (I can't tell if that's only for graphics software...). I made the switch to having a dual boot Win XP 32/64 bit system and it's a blast how much ZB can handle in 64bit, there's only one thing: I can't find much info on antivrus progs that are compatible with XP 64. Norton/Symantec doesn't support this config and I'm somewhat leery of some of the less well known vendors, so if anyone has any advice or thoughts, I'd be very appreciative. Thanks!,
