Thank you all for the replies.
I've tried removing it by simply commenting it out, but no change.
Assam, where would the parentheses go? I've fiddled with it but dont know
where. This is the block of code that i assume you are referring to:
XMonad.Actions.Volume
infixl 1 <*
(<*) :: Monad m => m a -> m b -> m a
pa <* pb = pa >>= \a -> pb >> return a

Thanks again
Dave
