I use avg internet security... never had any problem and openoffice... I tried it... and I uninstalled it IMMEDIATLY and deleted the installer... I HATED it... really... I wanted to make a graph in ... calc or whatever it's called, and I searched for half an hour how to change the cells from which it took its data / x-axis ; it would always select them automatically, and I couldn't change these things individually (i.e. one cells region for all data) ... Maybe I just didn't find it... but doing that with Excel (which I got the day after) took me 2 minutes... So yeah... it sucked real bad imo. Of course, I won't bash the product too much, cause it's free... for someone who doesn't want to pay for ms office, and would feel guilty of getting an illegal copy, then it's fine, but for anyone else, just get ms office... Most people using open office just hate microsoft for no apparent reason... these people annoy me... bleh
