From Bugzilla Helper: User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.0rc1) Gecko/20020417 BuildID: 2002041712 When Mozilla is activated (e.g., by clicking on its icon if it's already running) it should create a new window, as when launched, if there is no window open. This is standard MacOS X behavior, though it's easy to miss since it's NOT standard Classic MacOS behavior. Reproducible: Always Steps to Reproduce: 1.Launch Mozilla. 2.Close all windows. 3.Switch to another application, without quitting Mozilla. 4.Return to Mozilla, perhaps by clicking on the icon in the dock. Actual Results: No new window was spawned. Expected Results: New window should have been spawned, just as if it had been quit and relaunched. I can provide more information on this if necessary--I think an activated application gets an AppleEvent. Email me at chally@mac.com if you want me to dig up and provide more info.
