WMP 11 [beta 2] Ignoring Registry

Can anyone tell me why:

In WMP 10, When in the Library you could drop down the Library options menu and choose whether or not you wanted WMP to:

-Add music to playlist on double click

-Play track on double click

-Play all on double click

These options edit the registry value:

HKEY_USERS\S-1-5-21-760369723-3109637620-2365065613-1007\Software\Microsoft\MediaPlayer\Preferences

LibraryDoubleClickQueue = 1

These values are preserved when you upgrade to WMP 11 [beta 1] and are adhered to.

For some reason when upgrading from WMP 11 [Beta 1] to WMP 11 [Beta 2] these values are ignored. No matter how you change them the player ignores them; why

And why did Microsoft drop the option to access this function
