Changing Keyboard Language while having Object Dock run

I have problems changing my Keyboardlayout while running Objectdocks. I usualy change between german and english with a Keyboardshortcut which stopped working afther I installed wincustomuize and Objectdocks. I don't know which is responisble for that. But maybe someone knows how I could add some kind of change button to the Objectbar?

thx
