Hmm... there could be a couple different problems. First, I would check the top sash guide to make sure that isn't broken. The top sash guide in your case will probably be a nylon retainer installed on the two upper corners of your sash. They hold the balance in place so it doesn't shoot up in the window. If they are broken or damaged in some way, it may account for this issue. I would also make sure your take out clip is functioning properly.
