Thanks a lot ........ I've been struggling for an hour with that.

I'm trying to do an animation (image sequence). I've done them before OK, but I've just loaded Photoshop on a new PC and although I can load up the photos ok (file / scripts / load images into stack) the animation timeline doesnt appear across the bottom. Any ideas where it is ?????
