So I have Key F4 A M Close
in .fvwm2rc for closing any window on Alt-F4. But I want the xterm app to be exempt from such a treatment. W/ fvwm-2.6.5, this configuration has been working flawlessly for me: $ cat ~/.fvwm/.fvwm2rc Key F4 A M Close Key (XTerm) F4 A M -- $ grep allowSendEvents ~/.Xdefaults XTerm*allowSendEvents: true Today I've built fvwm from the master branch & have noticed that the above trick doesn't work any more--the xterm window gets closed when I press Alt-F4. What could be the culprit?
