With NOD32 and Outlook 2000, right clicking on an e-mail, click View Attatchment, and then clicking the attatchment, brings up an illegal operation in module unknown. This happens even with NOD disabled. When I uninstall NOD, the problem goes away. Most of my users are still on Office 2000, so I'd like to fix the problem instead of hearing them complain about opening attatchments. Anyone know of anything I can try? I can send a screenshot if necessary.
