Shane M Coughlan writes “Mobility Email Beta 4 has now been released. It is the fourth beta release of the portable distribution. It is stable enough for people to use as an every day email client. This version changes a configuration option in Mozilla Thunderbird to prevent crashes with the new in-line spell checker. Mobility Email is a full version of Mozilla Thunderbird 1.5b2 with added OpenPGP and Webmail extensions. It is portable, and can run from a USB drive without being installed on a computer.
