Jim, Be aware that rotating the zoom box of Richard's Fractint for Windows beta 5 (now renamed Iterated Dynamics -- and still not released for general use) distorts the zoom box contents by a factor of 4:3 and a function of the angle rotated. The zoom box can, however, easily be rotated 90 degrees and show a correct aspect ratio image -- if you follow the 90 degree rotation with manually shrinking the X direction by a factor of 0.75. Note that Richard adjusted the initial default M-set to show its correct aspect ratio. To see the aspect ratio problem caused by rotation: - let the program calculate the default M-set; - zoom in to get a zoom box ~80% of the full window size; - rotate that zoombox ~45 degrees, and - hit Enter to see the non-1:1 aspect ratio result -- the circular M-set bud is no longer circular. I also recall someone saying that they had trouble with the (V)iew command. In place of View, I simply use a different pixel size window/resolution. There's also a bug that is brought to life when using the formula: formulaname=MandelbrotBC3 (also perhaps in other cases) but I discovered what triggers it and created a work-around that works -- if the function "ident" is passed to the formula... I put my work-around, (and a slight speedup) & the assumptions it makes below. I haven't used all that great a variety of Fractint's capabilities in Richard's version, so I suspect that there are a few further anomalies hidden in it -- it is a "beta" release, after all. However, despite all of the above, essentially all of my thousands of images that are variations on your FoTD images -- posted on my web site: http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html were calculated by Richard's version of Fractint. I took great pains to verify that of Richard's Fractint for Windows beta 5 images exactly matched yours before I proceeded with creating my variations. ================================= Hal Lane's MandelbrotBC3 work around: ================================= frm:MandelbrotBC9 { ; by several Fractint users ; ; fn1() removed.

version of Fractint. Is there a version of Fractint that will run under XP and operate similar to the DOS version?
