My program have a "splash" window that shows before the "main" window.

On my machine (Windows 7) it works fine, but on my partner's machine (Windows 10) the program abruptly ends as soon as I call hide() on the splash window.

(On Linux and Mac it works ok, too.)

Any ideas?

    FLTK's Fl::run() returns when there's no windows open, so make sure you show()
    the main window just before hide()ing the splash window.

    I assume you're using an Fl::add_timeout() to trigger the mainwin->show() and
    splashwin->hide(), so just be sure to do them in that order.

    You want to avoid having /no window/ open even for a short time,
    or the event loop will think the app has completed.
