I use FVWM 2.6.4-2.1.2 on a couple openSUSE 12.2 systems. Frequently (perhaps half the time), when I select the Restart Fvwm2 entry (which just executes the Restart function), instead of restarting the window manager, it exits and the user is logged out. I experience this frequently. I modified my .xinitrc to make sure core files could be written, but no core file is dropped.
Since FVWM seems to leave no clues as to its demise, I'm at a loss to debug this problem. Any suggestions are much appreciated. Thx, Skip Montanaro
