My super key won't act as a modifier key in my Xemacs 21.4.15

[Bill Case]

Hi;

I am having trouble setting up modifier keys in Xemacs and I have been
unable to ascertain if it is an a) Xemacs problem; b) X Window System
problem; c) Fedora problem; or, d) a Bill stupidity problem. 

I have X Window System version 6.8.1 installed with my FC3.  It is fully
patched and or up to date as far as I can tell.

xmodmap pk shows Super_L and Super_R mapped to keycodes 115 and 116
respectively, as does the gnome keyboard layout gui.  When I run an
Xemacs command with "super f6" for example I get no response, unless I
purposefully mis-define (Super, S, or Super_L) global-set-key.  Then it
tells me I have a modifier error. i.e it seems to be recognizing super
as a modifier of some kind.  When I am in Xemacs, gnomes keybindings are
not relinquished and continue to do gnomish things.

My init.el contains the following:

(define-key global-map '(super f6) 'insert-date) and/or
(global-set-key '(super f6) 'insert-date)

The 'insert-date function works. I have tested it with other key
combinations using meta.  I have tried every possible combination of
super and f6, f, (),[] -- nothing works.

My shift key when used as a modifier key is wonky as well.

I have Fedora Core 3 installed and I had no problems with 'super' or
'shift' under RH9.  Any suggestions would be welcome.

Regards Bill
