Mike,

This tells me that the dropdown menu for a window still contains the
Alt-F4 key combination for a Close action; true?  If so, this must be
removed from the window menu.  This can be done either by using the
editor mentioned in the online documentation (URL sent earlier) or
by editing dtwmrc by hand and deleting the Alt<Key>F4 sequence from the
"Close" action line.

The instructions in the URL we sent previously came from SSEC.  Before
they provided these, I attacked the problem independently and came up
with the following modifications:

o edit .Xdefaults and set

  Dtwm*WindowMenu:    DtwmWindowMenu

o edit .dt/dtwmrc and end up with the following:

    <Key>SunFront               ifkey|icon|window       f.raise_lower
    <Key>SunOpen                ifkey|window            f.minimize
    <Key>SunOpen                ifkey|icon              f.normalize
#   Ctrl<Key>L2         ifkey|window        f.next_cmap
    Ctrl<Key>L4         ifkey|window        f.prev_cmap

Menu DtwmWindowMenu
{
    "Restore"   _R  f.normalize
    "Move"  _M  f.move
    "Size"  _S  f.resize
    "Minimize"  _n  f.minimize
    "Maximize"  _x  f.maximize
    "Lower" _L  f.lower
    no-label    f.separator
    "Close" _C  f.kill
}

My method removes all references to keyboard shortcuts for the window
menus, so I don't have the Alt<Key>F4 problem that you are reporting.

I have not run into this here.  My modified dtwmrc file lives in .dt.
