Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:22.214.171.124pre) Gecko/20100307 Lanikai/3.1b2pre The menu item View | Message Body As >> has been tweaked to change to View | Feed Message Body As >> when an RSS item is selected. However, when an RSS node (folder or account) is selected in the folder pane, the menu is reset to the older form. It does not reset if you select a message, then click on the current node, but changing the node (to another RSS node or some other type) does reset it. The menu should read View | Feed Message Body As >> when an RSS account or folder is selected in the folder pane, just as when an item in the thread pane has been selected. This is also the case in 3.03. Running 32-bit TB on 64-bit WinXP here.
fixed in Bug 596234.
