It always used to be the case that NSTimer firings didn't count as "real" events so the autorelease pool didn't drain if the only "events" in your app were timer events. As soon as you do something to fire a real event e.g. move the mouse or bring the app to the front, the autorelease pool drains. I guess the work around would be to create your own pool at the beginning of the timer firing code and drain it at the end. > > > > _______________________________________________ > > Cocoa-dev mailing list ([email protected]) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > http://lists.apple.com/mailman/options/cocoa-dev/adc%40jeremyp.net > > This email sent to [email protected] ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
