I have seen this in a few rare cases after a reboot, where all folders and files will have the Read Only Attribute. If you uncheck it, it will just come back. It is more of a filesystem issue in Windows than a configuration issue and it looks like when Windows detects a badly corrupted filesystem that it will make things read-only, sort of like Linux would. If you are Administrator or the owner of the folder and this is happening it is probably due to the reasoning mention........

Navigate to Tools -> Account Settings -> Server Settings Uncheck the following: "Check for new messages on startup" "Check for new messages every NN minutes" "Automatically download new messages". Source: http://forums.mozillazine.org/viewtopic.php?t=635510........

Tools -> Options -> OpenOffice Writer -> Table Uncheck "Number Recognition" This will permanently disable it but won't undo the damage it has already done. I spent a long-time fighting with this horrible feature which should be disabled by default.........
