Thx Greg.

Yes, win2_accountNoX was an effort to produce an alphanumeric spinner (I couldn't find one in fltk, I guess you could tell me if there is one).

    No spinner for alphanumerics, if I understand you correctly.
    Fl_Spinner AFAIK is numeric only.

    You can of course make a custom composite widget that derives
    from an Fl_Group with two up/down buttons around an Fl_Input widget,
    the up/down buttons invoke a callback that handles cycling the
    alphanumerics in the way you want, and you can provide methods
    that get/set the value. Fl_Input would both show the value and also
    let someone just go ahead and type it in.
 
    If that sounds useful we can advise, just describe how the alphanumeric
    aspect should work.

    It's be best if for this thread if you could reduce the app to just the FLTK
    code, without the non-FLTK stuff to demo the problem. So if the problem
    ist just with the win2 window's widgets, and the menu items aren't important,
    then reduce the test app to just that, so anyone here can build and run.

It did not display too well as you have noted but this morning I have re-coded that with

            win2_accountNo->color(0xE1E1E100);
            win2_accountNo->textcolor(0xE1E1E100);

which hides the the numeric value nicely.
