A few issues with Scribble (fantastic by the way) and Discourse. The reply pop-up box doesn’t play all that nicely with it. The little scribble icon pops up okay, but half the time the iPad seems to think you want to control the layer behind (with existing comments) and it scrolls up and down as you, well, scribble. There may be something I’m missing here but perhaps something for the main Discourse board?
