Hi Jean - I set No Houses using the Toolbar with the icons. I got the problem that Sindy has. It seems to be isolated to one off removal of the house system, rather than setting the default as No Houses through the Options menu.
My guess is the problem line is 154: getcirclepos(mx, my, height * .26, findr1 - asc, posx, posy);
Where asc is only defined in terms of planets[ASCENDANT]. This is probably vulnerable in the case above where this is not defined?
