Certain shortcuts don't work with Logitech Mac DiNovo keyboard

The shortcuts that have EJECT as a part of the combination don't work. There might be other shortcuts that don't work too, but this is what bothers me most.

The eject button does work on its own, and I'm not sure if the problem is related to the keyboard since it's the only keyboard I've used with this mac... I tried looking at all the preferences, etc. but I found nothing that helped. Ideas are appreciated.
