yes - that's pretty much the way I see it, except that I worry that it is fltk that is awry here, and it is our code that is multiplying the existing matrix rather than doing an explicit set... Only I don't know enough about this to know either way. -- Ian _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
