Hmm... I just rebuilt the LessTif package
using --enable-static --disable-shared and installed it.  I still get the
same problem where mwm runs and doesn't have the 100% CPU-time but, but it
still doesn't do anything when I click things (other than make the button
flash).

I ran cygcheck on this new mwm.exe and got:
$ cygcheck mwm.exe
Found: C:\cygwin\bin\mwm.exe
C:\cygwin\bin\mwm.exe
  .\libICE.dll
    C:\cygwin\bin\cygwin1.dll
      C:\WINNT\System32\KERNEL32.dll
        C:\WINNT\System32\NTDLL.DLL
  .\libSM.dll
  .\libX11.dll
  .\libXext.dll


So the libraries are indeed static in the new LessTif that I just built.
However, I became curious so I uninstalled the new LessTif (0.93.18-3) and
reinstalled the supposed shared library version of LessTif (0.93.18-2).  I
then ran cygcheck on this old mwm.exe and, lo, got the same results:

$ cygcheck mwm.exe
Found: .\mwm.exe
.\mwm.exe
  .\libICE.dll
    C:\cygwin\bin\cygwin1.dll
      C:\WINNT\System32\KERNEL32.dll
        C:\WINNT\System32\NTDLL.DLL
  .\libSM.dll
  .\libX11.dll
  .\libXext.dll


Thus the default settings for building LessTif on Cygwin must be to build
static libs only.  Therefore the LessTif 0.93.18-2 Cygwin package has static
libs.

This also means that my mwm.exe problems have nothing to do with shared libs
(since I've only been building static libs).

One interesting thing to note is that I can get mwm to switch between
virtual desktops by moving the mouse pointer to the edge of the screen.  The
window redraws correctly for the new virtual desktop and I can navigate back
to the original desktop.  However, I cannot move, resize, etc. the xterm
window.

Finally, I switched the prefix from /usr to /usr/X11R6.  I don't want to
release this new package until we can figure out why mwm isn't working for
me (as it will probably do the same for others).
