I sort of thought that applications should be neutral to Window managers.
However, I recently started using a CAD software tool (Cadence/Allegro) to
design a printed circuit board. I noticed lots of X-window-related crashes
and hangs so I switched to dtwm (under HP-UX). The crashing stopped, but I
am still not happy. My CAD support engineer found the following note on the
Cadence web site. Note that it is not the error I encountered. I would
appreciate any hints or suggestions anyone might share so that I could use
my favorite Window manager.

*Error_Message:
X Error of failed request: BadAccess (attempt to access private resource
denied)
Major opcode of failed request: 28 (X_GrabButton)
*Problem:
Middle/Right Mouse Button Function Crashes Over Cell in Library Manager
*Solution:
This error is generated because of Window Manager being used. If you use
a window manager which is not MOTIF compliant then this error appears. this
has already been reported on following.
fvwm, fvwm-2, KDE Windows Manager and R4 version of twm window manager.
for fvwm and fvwm2 , following changes in configuration can be tried.
The following two options should be specified in the fvwm configuration
file to mimic some motif behavior:
"MWMDecorHints"
Causes fvwm to read the MOTIF_WM_HINTS atom from application windows
and to parse and attempt to replicate the Motif behavior with regard
to window decorations. Note that mwm allows function hints to
affect
window decorations but these effects are not replicated by this
option.
"MWMFunctionHints"
Causes fvwm to read the MOTIF_WM_HINTS atom from application windows
and to parse and attempt to replicate the Motif behavior with regard
to allowed window functions. Unlike mwm, which simply removes
prohibited functions from the window's menus, fvwm simply shades out
the prohibited functions. Also, because fvwm implements some
functions
in user defined macros that mwm implements internally, the mapping
of
prohibited functions is partially based on the menu item label.
for KDE windows manager , following changes in configuration can be tried
Set Button3Grab=off in ~/.kde/share/config/kwmrc
Note : fvwm/fvwm2/KDE windows manager/twm(version R4) are not supported
Windows
Manager for cadence applications. It is
highly recommended to switch to motif or openlook windows manager.
