the setup menu:

from this menu you can do
two things:
 1. change the internal mouse
    driver
 2. change the game delay

Internal Mouse Driver:
included with Ancients are
two different internal mouse
drivers. The default driver works
with microsoft-compatable mice.
Some third party mice are not
totally microsoft compatable.
If you experience difficulty
using your mouse, try toggling
the mouse driver while in
the setup menu.

Game Delay:
the delay time determines the
rate at which text is displayed
in the text window. First time
players should have a high delay,
while pros may wish to speed up
combat by not having a delay at
all.
