I opened Pages earlier and it said there was an update. I didn't have time then so I dismissed and told it not to remind me about that update again. Now Software Update isn't showing anything for it or iWork and I can't see anything on Apple's Downloads page. How are apps "registered" with Software Update (so it knows to look for updates for them) because I remember having a similar problem before? My Pages version is 4.0 (727). Is there actually a later version?
