I've noticed that you can't jump as high in Vavoom as you can in the original Hexen. This does cause some problems. Particularly on the second level Seven Portals in the Guardian of Steel where you need to jump on the ledge in the central area. Also, you can't jump to the ledge on the windows on either side of the area. I'm using the latest version of Vavoom with all the sprite downloads and glvis for doom1 and 2, heretic and hexen. Could you please add a little height to the jumps?
