Change Mac to English (UK) instead of English (USA)?
I'm running on OS X (just shy of Snow Leopard).

So I guess a Snow Leopard answer to the OP is to go to SysPrefs/Lang&Text/Text and set the Dictionary to British English there and then it would be set universally throughout the system.
But I just did a number of tests with changing the preferences in Sys Prefs/Int'l/Languages, logging out and logging in and I did not find that the setting has done anything to change the dictionary used for spell checking. Not between the different versions of English, and not when I switched to Spanish.
Using TextEdit I am not getting the behavior you expect.
