dang! sorry to hear it. I've got whatever QT is the latest (OS X). one would venture the conclusion that APS is still a mac-centric app, after all these years. anyway, once ya get it to work, then it appears as in the attached image. it has an animation window, and when one clicks the "play" arrow, it runs thru the cels in the anim-window, and plays in the main window and navig-window.
