What does 'xmodmap -pm' show?  Mine gives:

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x6d)
mod1        Alt_L (0x40),  Alt_R (0x71)
mod2        Num_Lock (0x4d)
mod4        Meta_L (0x73),  Meta_R (0x74)
mod5        Scroll_Lock (0x4e)

Notice Num_Lock is assigned to mod2.  This means that the Num_Lock key
is a modifier key just like shift, ctrl, alt.  So if Num_Lock is on
then if you use Alt-F you are really doing Num_Lock-Alt-F. If you don't
want Num_Lock to be a modifier you can disable it with xmodmap.

xmodmap -e "clear mod2"

See the xmodmap man page for more info.

Debian's default X setup will read ~/.Xmodmap on startup so if you put 
'clear mod2'(no quotes) in that file it will be taken care of
