I have the sound and mouse, but no gameplay lock up too. Just wanted to add that my problems started ocurring after dropping the freight train addition to my trade port which seemed to be operating for a while without hassles.
My game freezes up after less than a minute in one city. The rest are fine, but this is totally unacceptable. The music plays and I can move the mouse, but the game is frozen.
FIX THIS. The game is broken. One free game is not enough for the frustration this Broken Simcity "game" has caused.
