this is a screenshot of a semi-quick "circle" type object. As you can see I still get the straight line effect, and this is with both a graphire and a usb optical logitech mouse. Spacing is set to zero (not off, as that just adds spacing anyways) It's not due to a slow computer either. I run a P4 2ghz 80gig hd (7200rpm) 64meg Radeon video card, with 512 ddr ram, and 70% memory dedicated to photoshop, which averages out usually to between 350-400 megs of ddr ram. Maybe it's time to try project Dogwaffle for raster illustration, as i Hate painter.
