After rereading your original post, Wooberman, a question occurred to me: how long do you average between game sessions? If your players are getting confused as to what's going on, it could be because of the gap between stories. A couple of my friends have the same problem because they often go weeks or even months between games. They frequently have to explain to us what we're doing, who we're fighting, and why. Players can also become confused if they're involved in multiple games with different characters and storylines. If this is your situation, I'd suggest having a brief Q&A before each new session, just to clear things up. I might also start keeping a log of the previous sessions, or elect somebody to be the secretary and summarize events as they occur. That way, if there are questions, you can simply tell the players to look back over their quest log.
