Exec is in there twice, as FVWM requests it to avoid doubling the number of process running. Per the man page, it is reccomended although not necessarily needed. Hence, I heed the man page advice so it is in there.
I noticed your commands issued have options added, which I have no problems with FVWM executing either. it is the setting of environment variables before the actual command (oowriter in my case) that is causing trouble.
So, with that, any more suggestions? Anyone? Buehler?
