Unfortunately such is the demand you have to keep up with the Jones's so-to-speak to have a sniff of a chance.
And in defence of those who do this, and I include myself (though it's only 3 windows ;o), once you're in on one browser and get your tickets, the others become irrelevant and by closing them it should boost you up in the line by that number of places. So if I only have one window loaded and you're directly behind me in line, it makes no difference if I have 5 open and close them all once I have tickets. You're still next.
Think of it as having a group of 5 people stood in front of you at a fast food queue. If only one of them is actually buying a meal, you'll get to the front just as quick.
