New feature, random message selection
There is a thread on the Virgin forum which has a post from a Virgin person that basically says that the new super-crappy email system is the same system that Virgin and Liberty Global use in-house. If they are happy to use such an inferior product on a daily basis then there is probably zero chance of the many bugs getting removed.
My favorite bug is the one in webmail that causes a message to be selected, more-or-less at random, when the scrollbar is moved in the message window. If you are lucky it selects one in the visible part of the folder so you can unselect it. If you are UNlucky then it selects one that you cannot see so when you delete or move another message the one that was selected by the system will also move or be deleted.
