What´s new in 4.1.1.9 since 4.1.1.8:
[ - ] If the %APPDATA% environment variable was not available (e.g under Windows NT 4.0), The Bat! now offers to create a mail directory in %USERPROFILE% or in the "MAIL" directory;
[ - ] Bugs related to "KillTimer" might harm execution of The Bat! on Windows NT 4.0 machines;
[ - ] MailTicker couldn´t get updated sometimes;
[ - ] (Beta) Automatically created (by filters and Mass Mailing) HTML messages could use wrong character set.
