How do I modify .mwmrc file for modifier keys?

[Billy Ng]

For HP 10.2 Unix, when I press on any modifer key (including the
NumLock key), the X-windows are not movable and cannot come to the
front. I think there is a problem in the Motif window manager which
is confused with the modifer key. My solution is to replicate the
exisitng setting of the mouse buttons in .mwmrc at the home directory.
For example,
window f.move
Mod2 window f.move

(Assumed that the NumLock key is assigned for Mod2 (modifier) key)

For the setting above, I can make the window movable when NumLock is
on. However, the window does not come to front.
I can also make the window "coming to the front" by replacing f.move
with f.raise. However, the window is not movable this time.
How can I make the window "coming to the front" and movable??

Thanks a million!!!
