My search on this site and on google only got me the Sims 3 version of No Autonomous Computer Games, but what I'm looking for is a Sims 2 version of No Autonomous Computer Games.

In Sims 2 the Sims are always on the computer, and even though I cancel the action they are still on the computer. Missing the carpool, missing the school bus, about to die from starvation..,

Autonomous computer fixes by TwoJeffs: http://www.simbology.com/smf/index.php?topic=13.0 It has a version that stops all autonomous computer actions.

I am using this mod and sims still keep playing on computer...

In several of my sim homes they were pretty bad about wanting to be on the computer ALL! the dang time. I started turning it backwards unless the computer was needed. Frustrated those sims, kept me from being frustrated, lol :-)

The most useful thing about that hack for me is the no waving and complaining because you can't use the computer chair (because someone else is fricking using it, you idiot!). XD

Do you want no autonomous computer GAMES or no autonomous computer USE?

If you want no autonomous computer use at all, you can try Squinge's mod "No Autonomous Computer" (http://www.insimenator.org/showthread.php?t=7254). This requires OFB which you seem to have. There are a couple different flavors of the mods.

You can also try Squinge's "No computer abuse" (http://www.insimenator.org/showthread.php?t=7022) also requiring OFB, but this one seems to only take effect when shops are open.
