EDIT> Never mind. Eventually the Colemak layout turned up in the UK locale's list (after the machine went into standby!)
============
I've installed the Beta Colemak layout on my Vista Machine, but can't add it to the English (United Kingdom) locale. It only seems possible to have it under the English (United States) locale.
I can add other US layouts to the English (United Kingdom) locale - see:

Is there a way to get around this?
