Thanks, Matt. I'm of course using defines for my only notification name. I'm suspecting it's my code as well but it's fairly straightforward. I'll revise my code and see what I can do but I was afraid that in the case of NSNotificationCenter, there wasn't much I could do, hence my question. Maybe will override some methods through a protocol to see if some of the steps are working as they should. If anybody has any insight, suggestions are welcomed. -Laurent. -- Laurent Daudelin AIM/iChat/Skype:LaurentDaudelin http://www.nemesys-soft.com/ Logiciels Nemesys Software laur...@nemesys-soft.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
