I generally run on 8-bit 1024x768 screens, and that would be what I used for View. The scrolling was much slower than on other programs, such as the Voyager web browser, running on the same screen mode. As Voyager is loading and assembling 24-bit JPEGs, it must have similar tasks to perform. Surely you don't have to do C2P conversion for a CGFX display?

Well, no doubt it will be usable with faster processors, but I feel there is something wrong somewhere. A program ought to run at a good speed on a 68060 with a graphics card. PS tried it again, but this time I couldn't get it to open on its own screen. No tooltypes, no ASL screen requester, no preferences menu. Just a very ugly window on the workbench in what looked like 8 colours, with no dithering or anti-aliasing. There was a big bright green square at the bottom left, for some reason. It looked like it was just using RGBYMC white and black. Next to the GlowIcons in the WB windows, this looks bad. I really want Rebol to succeed, but it will have to present better than this.
