[i]Please note: Only issues experienced by a reasonably large number if users are included. Only issues reported by users, and generally only those reported in the bugs/issues forum and ‘format verified’ or reported by mods, are included. Issues are included if I believe they represent a significant problem to users - developers may not regard all the issues below as bugs. Vulnerabilities to specific exploits are not included for security reasons, though more general areas of vulnerability are. Issues present in previous versions will be included unless I have been told, or have observed that they have been resolved. Issues listed above should not therefore be regarded as confirmed current bugs by Comodo.
