Sometimes when I select a animation, in the previewbox and the game (It's usally an Animated GIF) The first frame of the animation, ends up in the preview box, but the rest of the frames are way out of the previewbox!
In the game the first frame is in one spot, and the rest of the frames are in another!
... Strange... I never use compiled gifs, always .png sets... no problems here. The gif format has different compiled versions, don't really remember the differences between the 87a and 89 (is that right?) versions though... so it could be how it was saved....
