Merged [18327]: Don't ever use the Tiger-only {{{-[NSPopUpButton selectItemWithTag:]}}}, as it returns YES regardless of whether or not the menu had an item with the specified tag. I've reported this bug in rdar://
4854601 - we'll use our 10.3-compatibility method, which does work properly in 10.3 and 10.4, fixing some oddities in behavior in a couple places, notably the Appearance->Customize Layout sheet when changing contact or group text alignment.
