When trying to edit the name,description and group name for site content type in MOSS B2TR, you might encountered the following error: "The resource object with key 'cyptedit_select_group' was not found."
Solution:
1) Edit "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\ctypedit.aspx"
2) Search and replace, "cyptedit_select_group" with "ctypedit_select_group"
That should fix it!
