Yeah! If memory serves me correctly, go to "Options" and hit "enable
mouselook" or something like that.
If that fails you, at the console type "+ mlook". That should do the trick.
BTW, both of these are in the manual, I believe.
I've been wondering the same thing...

I put +mlook in the autoexec.cfg file.
I poked around and figured it out. You have to go to the command line and
type "+mlook". This was not documented anywhere I could find, but I was able
to get the list (without explanations, by the way) of commands by typing
"commands" at the command prompt. This created a txt file called
commands.txt which lists them all. I don't know if this works with versions
other than 1.11 (the latest patch), but now everything is smooth. I'm a
happy Hexen II player.
