Mac OS Mail (the Tiger version) has suddenly gone completely weird on my Cube. It's OK on my iMac (Leopard) and my iPhone, but on the Cube, if I click on a header I get a completely different message, belonging to another header. It's like the whole thing has gone out of sync. Come to think of it, the same sort of thing has been happening on the Cube with iPhoto for some time now: if I search in Spotlight for an iPhoto file, it will open up the first image in my iPhoto Library, regardless of which image it should be finding. It's as if all the metadata has been corrupted somehow in both programs. I've already tried rebuilding the Spotlight index, with no effect. Any other ideas?
