If you TAB while the mouse is down, I'm not sure what our code will do. The player may send focus to the browser and then you'll get a deactivate event. These problems are hard to debug because even going to the debugger causes a DEACTIVATE event.

By doing so I witness that "onDeactivate" event handler is fired every time I move via keyboard tabbing to a new itemEditor. -- Best regards, Andriy Panas 2009/4/20 Alex Harui <[email protected]<mailto:aharui%40adobe.com>>: > > > DEACTIVATE is used to detect that the browser or some other application is > taking focus so we close any editor that may be up.
