Only closing all windows ends the Fl::run() call. You probably generate the ESC key at some point which then closes the main window, exiting the Fl:run() loop. The easiest way around that is to set a callback for your main window. The callback can do nothing. The default callback hides the window when ESC is pressed or a close event is generated somehow (clicking the close icon etc.). > Another interesting fact, is that using Fl_Box(or even Fl_Label or Fl_Button) > to draw label could be slow(at least in my software).

Remember that if you use outside labels, not only the widget is redrawn, but all widgets within that group. If you have hundreds of widgets in a group, and a single widget in there changes its "outside" label, all others are redrawn as well.
