Autonomous Computer Fixes
There are two versions in the archive. Normal and No Autonomy. Only install one of them. This probably conflicts with other computer type hacks. It doesn't conflict with anything in my game though. I'd recommend running HCDU if you have any. Features:

    * Computer in use check made smarter. Also added check to see if chair is
   available.
    * Sims who do attempt to use a computer whose chair becomes occupied
 will quietly find something else to do and not insist on whining to you about it.
    * All new FT computer options are disabled for visitors on residential lots.
    * No autonomous turning off the computer.
    * Sims will only autonomously check e-mail if there is e-mail on the
 computer to be checked.
    * Autonomous socials are disabled while using the computer (other sims will
not be obsessed with talking to them).
    * Sims giving financial consulting who have the interaction cancelled for
any reason will recieve partial credit ($$) for the amount of time spent instead of getting hosed.
    * No autonomy version will disable autonomy from Chat, Gaming and
gaming competitions, Web surfing/blogging, checking e-mail.
