The maxscript help for 3dsMax 2012 has gone online. By default, 3dsMax doesn't ship with a local help for mascript and for the main program. When pressing the F1 key, your browser opens and finds the help online. This has its advantages and disadvantages. A big disadvantage is that you need an internet-connection, and if you have one, it needs to be fast. For many people this is a reason to download the help-files and use the local version instead.
