Hi ! Having updated some client machines to FC4 last week, the users are complaining that Thunderbird won't open attachment documents properly. They double-click on the attachment and get offered the "What do you want me to open this attachment with" dialogue, pointing to their home directories. One machine was a clean FC4 install, but using the same shared home directory that had been used by the user's old FC3-T4 machine. The other was an FC2->FC4 upgrade, again using the user's old shared home directory (this time from FC2). Is this a home-directory and settings issue, or has anyone else had this problem with attachments ? I have a new machine on order to put FC4 on myself tomorrow, but I'd appreciate any thoughts from the group before I get started ... Jonathan
