The delete_widget() method, as documented, is supposed to handle the important special case of deletion from within a callback. It was thoughtful of the designers to think of this. As for being "not supposed to delete FLTK widgets..," if this were really the case (and, with due respect to Greg, I really doubt it), fltk would simply be broken. So long as the OP's code isn't in a callback, and his win isn't a subwindow, it should be fine, and shouldn't leak any memory.
