    Hm. Since `fdesign' is based on XForms and calls fl_initialize() at
    startup, it seems to me that if it works your app should work, too.

    Can you provide a traceback?

    Are you setting any unusual options when with fl_set_defaults() before
    calling fl_initialize()?

    `fdesign' asks for the default Visual, turns off double buffering,
    sets the browser font size, and asks for a shared colormap:

        cntl.vclass = FL_DefaultVisual;
        cntl.doubleBuffer = 0;
        cntl.browserFontSize = FL_NORMAL_FONT;
        mask = FL_PDVisual | FL_PDDouble | FL_PDBrowserFontSize;

        cntl.sharedColormap = 1;
        mask |= FL_PDSharedMap;

        fl_set_defaults(mask, &cntl);

    then calls fl_initialize() in the standard manner.
