I did. It's quite straight-forward: replace the menues, mouse bindings and key bindings to do nothing. Use FvwmButtons as an application launcher or run just one application by default (your choice). It's a good idea to place a supervisor in the backgound, that kills all applications but the ones you want to be run. Nik
