Thanks for all the responses everyone. I especially like the "delay" action.
Regarding the player in question, I believe he has a basic understanding of the rules, but much more of an understanding than a newbie would. This is his first time gaming with a live group, but he appears to have settled in fairly well.
The problem is that he is the type to go off on "tangents". When I first met him, he explained that he has a problem paying attention if things don't concern him or he doesn't find interesting. He explained that he would walk around or be a bit fidgity (sp?). In otherwords, he is a bit socially inept.
I didn't mind because we are all people and just because someone is socially inept doesn't mean that can't play DND.
Anyways, when it is his turn at combat I believe it is a mixture of having the spotlight on him, not being sure what he wants to do, the amount of options available, and the pressure of have to make a decision.
Last session, when it was his turn, his character was surrounded. Basically, he could have either attacked or withdrew. He started going of another "tangent" talking about this or that. Everyone at the table gave hints on what he could do, like withdraw. A few minutes had already passed at this point. Finally, I got fed up when he started talking about "I think we need a net" when there was no way that were going to get a net at the very moment in time. That is when I skipped his turn.
