No. Characters never wait for rounds to end. Rounds are 6 seconds. If the characters went by rounds it would be never be possible to move or attack after casting, you would have to wait until 6 seconds after you begun casting the spell to move. But in IE you can in fact make a character do arbitrarily many actions within any 6 second period, so that is clearly not the case. The only thing 'round based' is spell casting, which can only be done once every 6 seconds. Everything else has nothing to do with rounds.
You are wrong. It is as has been said, IE games work on 6 second rounds, only everyone gets his round at the same time. Use an item, e.g. drink a potion. Then drink another one. You character will wait for the next round, only then he'll drink the second potion. The same applies for spells/using a wand or any other form of action except moving. There is no *move*-action in IE games. You can always move, before casting a spell, after casting a spell. It doesn't matter. If you cast a spell and have seconds left in that round you can attack and move - if you have attacks left for that round. Otherwise you can just move. Anyway, the fact that IE games don't treat moving as standard action that can be taken only once per round as per DnD doesn't mean that the game doesn't work on 6 second rounds - it does in fact.
