Found the solution!! The problem was here:
> if (Math.abs((stage.mouseY-stage.height/2)/100)>0.2) {
> camera.tilt(((stage.mouseY-stage.height/2)/100));
> }
> if (Math.abs((stage.mouseX-stage.width/2)/100)>0.2) {
> camera.pan(((stage.mouseX-stage.width/2)/100));
> }
when MovieMaterial was interactive=true and mouse was over it,
stage.width was some value, but when mouse was out of this clip
stage.width ang height was about 1000 times higher. I used
stage.stageWidth and stageHeight and that gave me always real screen
dimension. but what is still strange for me that when there is no
interactive moviematerial stage.width/height returns real values
(800x600).
btw. thanks for trying to help :)
