Mwm menus and window controls sometimes do not work when Num_Lock is on.

There are two ways to fix this: 
modify the .mwmrc file so that the button bindings
are defined to work with the Num_Lock modifier. A sample is below.

Or, use xmodmap to clear the Num_Lock modifier.

In either case, use xmodmap to see what the Num_Lock modifier is:

For example, on a DG system, the xmodmap output is:

% xmodmap
xmodmap:  up to 2 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x12),  Shift_R (0x59)
lock        Caps_Lock (0x11)
control     Control_L (0x14),  Control_R (0x58)
mod1        Alt_L (0x19),  Alt_R (0x39)
mod2
mod3
mod4        Num_Lock (0x76)
mod5


Use the command:

% xmodmap -e 'clear mod4'

to clear the modifier.

On SCO, the Num_Lock is mod2, and you would use the following button
bindings to fix it.

*** Sample button bindings for .mwmrc ***


# Prevent NumLock (=Mod2 on SCO server) from interfering with bindings.

    Mod2 <Btn1Down>             root            f.menu  RootMenu
    Mod2 <Btn3Down>             root            f.menu  RootMenu
    Mod2 <Btn1Down>             frame           f.raise
    Mod2 <Btn2Down>             frame|icon      f.post_wmenu
    Mod2 <Btn3Down>             frame|icon      f.post_wmenu
    Mod2 Meta<Btn1Down>         icon|window     f.raise_lower
    Mod2 Meta<Btn3Down>         icon|window     f.move
