Hello,
It seems grops and grohtml are not working for me on Windows Vista even with UAC disabled. this command: groff -p hello.pic > hello.ps results in: grops<standard input>:4:fatal error: fdopen: Invalid argument the command: groff -Thtml -p hello.pic > hello.ps results in: pre-grohtml:fatal error: fdopen: Invalid argument the command: groff -Tdvi -p hello.pic > hello.dvi does work. The exact same commands on my Windows XP machine work fine. I'm using groff-1.20.1. Any tips? Thanks, Boudewijn
