I've just tested netscape without the overriding translations and it works fine, with just keycode 22 = BackSpace.
However, this is only true if I invoke it from the shell. If it's invoked from fvwm backspace doesn't work, with or without the translations. Here's what I use to call netscape (I don't use the debian package): #!/bin/sh XNLSPATH=/usr/local/netscape112/nls \ XKEYSYMDB=/usr/local/netscape112/XKeysymDB \ /usr/local/netscape112/netscape $* Carlos
