If i understood ok, you are saying to use fl_set_form_dblbuffer before
fl_show_form. This is what i am doing. ( Did i mentioned that my form
has a canvas???? If i did, im sorry, my form has 2 free objects on it...)
Also I haven't manage to deactivate my form yet while drawing. Any suggestions
about this????
Thanks for your (precious) time...
