First of all, I am trying to understand what questions I need to be ask in order to solve this problem. I work for a small newspaper in the advertising department. We have great difficulty in downloading ads that are e-mailed to us from customers. We are using Mac G773's, and the e-mail application being used is Outlook Express. What happens quite often is that an error message comes up "file corrupted" or "file cannot be opened". Other times when downloading rather large files, a message comes up "disconnected due to lack of activity." When this happens, we download to the one and only new iMac in the building and then transfer the files to the desktop of the G773's. Is there someone willing to help me sort this out?
