Good point, I had similar reports already, but I simply forgot to handle this 
in yesterday's release. The right way to handle this would probably be 
extending the MouseButton data type with an 'AdditionalButton Int' constructor 
and simply pass the unknown button numbers via this case. I am not so sure 
about a nice name for this constructor: AdditionalButton? GenericButton? Or 
simply MouseButton, just like the type itself?
