I have *never* added or removed any object other than self in the notification center. I would rather rearchitect some other aspect of my app to get messages passed around than break this rule. Actually, I did it once and became hopelessly confused: my notification was never arriving and I didn't know why, and I couldn't easily find out because you can't query the notification center as to what observers it's got registered. Eventually it turned out that some other object was unregistering me behind my back. So since that day I have followed the above rule and have been a happy camper. I'm not saying it isn't possible, I'm not saying you shouldn't do it, I'm just saying. :) m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
