So... I have a 2009 Mac mini, with FRESH Snow Leopard 10.6.1, ALL iLife etc updates... been working on a movie for 1/2 an hour, when... POP!! iMovie decides it has had enough, and quits without warning!. Well done, that's a ****ing ******** of work I cannot be bothered to do AGAIN. Thanks a lot, I now have to work out why (and yes, I repaired ALL my permissions, it is a FRESH install, as I said). One thing here is.... WTF?!!
