An update to hUb was just released. This release includes the ability for hUb to remember your login credentials, or if you prefer to play anonymously, and go directly to the game list when you start hUb the next time. There are also some other improvements to the login dialog. The problem on vista where the window border was not properly drawn after exiting a game has also been fixed.
This update is automatically installed the next time your run hUb.
