It sounds like Fractint is not finding the formula. If you are keeping it in a PAR file make sure there is an frm: in front of the formula name. Otherwise make sure the formula is in a directory and file that Fractint will search for formulas.

Cracked the problem: Normally I paste the par entry, (including the frm: formula), from Jim's FOTD onto the end of my current FOTD par collection. This has always worked fine in the past. But it looks like Fractint takes the first occurrence of the frm entry in the file and uses that. So we had frm:MandelbrotMix3 {; Jim Muth z=p5, c=pixel, a=real(p1), b=imag(p1), d=real(p2), f=imag(p2), g=real(p3), h=imag(p3), j=real(p4), k=imag(p4): z=(a*(z^b))+(d*(z^f))+(g*(z^h))+(j*(z^k))+c, |z| <= 100 for the FOTD on 19-02 (this give the rather fetching blue screen with the 22-02 par entry) and frm:MandelbrotMix3 {; Jim Muth z=real(p5), c=fn1(pixel), a=real(p1), b=imag(p1), d=real(p2), f=imag(p2), g=real(p3), h=imag(p3), j=real(p4), k=imag(p4), l=imag(p5)+100: z=(a*(z^b))+(d*(z^f))+(g*(z^h))+(j*(z^k))+c, |z| <=l } for the problem FOTD on 22-02 A quick rename to MandelbrotMix3a in both the par entry and frm definition solved the problem. Thanks for the help. Regards, Chris
