That has absolutely nothing to do with what I am talking about.
Minecraft has command line options. You can start Minecraft with certain appendixes in the command line to make the client automatically log in (so you land directly in the main menu when starting up the client) or even automatically connect to a server (so you land directly on a server when starting up the client). These are broken in1 .2.1 and 1.2.2, they simply do not work anymore.
Ok thank you for this information; I will add it to the bug list.
