Lately I've been noticing SC2 is taking a lot more RAM that it is suppose to. It would normally be around 500MB - 1GB. Now when i play it slowly rises until all my RAM is gone and i get that annoying message that says windows 7 recommends me to close SC2. Sometimes my computer would even freeze up and will not respond to anything but a force restarted. Anyone else have this problem or hopefully a solution?
