Outlook 2007 recently started having a problem with the ESET plugin. Outlook reports a problem, asks if I want to disable the plugin but the disable window keeps popping up. Can't close Outlook, only way to get rid of it is to restart the OS which goes without a problem. On Outlook startup, I tried to renable, but go the same problem and have had to disable the plugin. Since then, obviously, no problem. I say recently. I've only been running the two together for a couple of days.
