by updating to the last version (7.1 20100106zi), we can sort comments by date or author. The comment list’s first comment defines the default comment author for current entity (class, package, …). This is workaround which helps me now, but is not really convenient.
I would like to let you know the author name problem has been fixed and please run the VP Suite Update to update the software to latest patch (20100908ze or later). Details about update to latest patch can be found at
Feel free to contact me if you require any further information.
