Shift + Bkspace restarts X11

I don’t know, which part in my Fvwm-Config is responsible. When i hit Shift + Backspace, X11 restarts. Ctrl+Alt+Backspace doesn’t restart the X-server.

Whe I start for example openbox, nothing happens with Shift+Backspace, and X11 restarts with Ctrl+Alt+Backspace.

Do you have any Idea, which command in the config makes this habbit?


It was a strange .Xmodmap from Debian… Found this in a Forum coincidencely…

Thanks for watching.
