Hmm... Mine works.

Are you using the latest version of Bartender3? ( http://files.wowace.com/Bartender3/Bartender3.zip )

Straight from my working macro:
Code:
/clearfocus
/focus [mod:ctrl,mod:alt,nomod:shift,target=Härem][mod:alt,mod:shift,nomod:ctrl,target=Hårem][mod:ctrl,mod:alt,mod:shift,target=Hárem][mod:ctrl,nomod:alt,nomod:shift,target=Hârem]
/stopmacro [modifier]
/click BT3Button107
And it works.
