jackie, when an image is view in halves 4ths 8ths and 16ths (etc), the image should look sharp. When viewing in intermediate areas, like 33% and 66%, the image will look jagged. That's normal, I've seen it since v5.0, and thats only because thats hwen i started using photoshop. and whatever happened to linux, hmmmm? Retro for what its worth, here's m rig. Photoshop 7 Windows XP Home Ati Radeon 7000 powering a 19 inch samsung flatscreen (1600x1200) and a cruddy tv (1024x768, plus a Voodoo3 video card at 1152x864 (which i only use for tool bars and menus, all displayed work is on the samsung). I get the "squared circles" with my graphire and with a regular usb optical mouse (both plugged into usb 2.0 ports, so there isnt any possibility of lag cuz they are both designed for usb 1.1). I got 512 ddr ram, and it happens whther Im playing Unreal Tournament or running nothing other than photoshop. I donate 70% available memory to photoshop, about 350-400 megs at any given time of my ram.
