Computer no-run glitch?

[Re-Peat]

I was playing the computer today and a strange thing happened.  The computer had a runner at first and it hit a grounder that went right over third and rolled into foul territory for a fair ball.  I ran straight left with my 3B to grab it in foul territory and threw it to second to try to get the force out.  Well, the computer runner was right in front of first base still, with the batter already on base.  He hadn't made a move towards 2nd at all.  Even if this wasn't a grounder and just looked like it, the player should have started running after the ball bounced and I fielded it... but it did not.

Weird, no?

he wanted a 3 way with the 1B and the batter.

I got one, maybe not new to you guys but was new to me and I've played tons or RBI.  I had a runner on second base and hit a foul ball out past third base in shallow outfield.  I went to tag up from second for the heck of it and the computer did not throw the ball to third, just held it.  I did try and then round third to score and they threw the ball home to prevent me from scoring but I thought it very odd that they didn't throw to third as I tagged up.

that "no throw on a tag-up" happens a lot.  i play against the computer all the time.
