GoldDisk Professional Draw works great - change tooltypes to INTERLACE=ON, COLORMODE=COLOR. Use Modepro to promote screen to 640x480. Run Blitzen first to clean up the pulldown color selection menus. Note that importing .EPSF files doesn't seem to work. Fontmanager 1.0 and Clipmap 1.0 also seem to work. CGUpdate locks up with OS4.1 u5.
