Installed NAS, no problems, then rebooted. Invoked Eudora 5.1. Got the message "NAS has detected that COM automation is turned off, would you like to enable COM automation?" I click yes, then close Eudora as directed and reinvoke - same problem. When I look in Eudora's configurations, COM automation IS turned on.Went to Symmatec's web site and did a search for the problem. There is an entry in their automated system about this and they basically say its a known problem with no solution at this time. They claim the problem occurs when you do not use the default folder for storing your mail files - I use the default.Bottom line - Symmantec acknowledges a problem with Eudora that has not solution. I do have a pretty yellow box sitting on my desk - AntiSpam my eye!! It's completely useless.
