Hi, Looking at the fractint.frm which comes with xfractint 3.10, the "bjax" formula is: Bjax {; z=c=2/pixel: z =(1/((z^(real(p1)))*(c^(real(p2))))*c) + c } This looks like it's missing a bailout condition. Does fractint supply a default bailout function if the user doesn't give one? When I render it I get a blank screen. However even if I add |z| < 4 at the end, it still doesn't display anything, so I'm a bit confused. Regards, -- Edwin
