I am having issues with Alias SketchBook Pro 2.0 on my Macbook. When I try and draw on the canvas the images do not show up. It's only when the canvas is refreshed, the images do appear. (E.g. A program window is placed in front of the canvas) I have installed Alias SketchBook 2.0 on my iBook and I have no issues with this program. Is there a bug with SketchBook when using Intel Macs?
