Truly I believe Fl:run() needs to be used only once, assuming you continuously have at least one window in use. Fl:run() is essentially just a way for Fltk to stay alive...as long as there is an active window, Fltk waits. When all windows have been closed, Fltk quits.

There shouldn't be a problem opening as many windows as you want. The biggest issue in my opinion is the organization and separation of those windows within your code. Make sure your windows have unique names. If you have them all in the same level (Global table) in the same script, or loaded as code chunks into the same level, include fltk:Fl_End() to tell Fltk where each window group ends. I'd suggest either sticking with modules or other form of loaded file, as you are doing now, or creating a table for each window. If you have your windows all uniquely named and separated, you should be able to open and close them at will with show() and hide().
