Thanks for that great explanation. Your issues about not supporting the native OS cursors and thus having to track down your own (which then don't match the native OS) also bothered me I'd like to see support of at least the minimum set of cursors defined in CSS2 via the flash player.
On that thought I was just wondering if it was possible to use the ExternalInterface to do this? By maybe setting a classname on the Flash object via JavaScript... hmmmmm -D --- In [email protected], "Troy Gilbert" <[EMAIL PROTECTED]> wrote: > > > I wondered if anyone else had experienced similar issues? > > What you're seeing is your app's actual framerate.
