I've had similar problems with a UINavigationController on iPhone where if there's a memory warning while the root view is hidden and the app is in the background the nav bar stack is messed up when we resume the app. My solution is to implement didReceiveMemoryWarning and just return, thus preventing the root view from being unloaded. You can call *that* a hack if you like, but my attitude is, hey iOS, if you're not going manage memory correctly I'm not going to let you mess with memory at all. Anyway, what I'm suggesting is that you try that sort of thing, to see if you can prevent the split view and its subcontrollers from having their views unloaded. m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
