I just realized. Originally when the MAS came out, Pages, Numbers, and iPhoto showed up as purchased because I had them when it was installed (I purchased iWork and iLife). This was supposed to be normal for Apple applications at that time. Now none of them are labeled as purchased, and thus not getting any updates . . . I wasn't paying attention to this, I thought I was good to go, but now I don't know. Anyone else experiencing this?
