Itunes doesnt have a horizontal scroll bar?

today there isnt a horizontal scroll bar so i cant buy and songs cos i cant see them without scrolling. never happened before, how can i fix this?|||Ok, I have the same problem. The only thing I could figure out that works is click down on the wheel, on your mouse (for scrolling), and a directional arrow thingy should come up; and scroll across the screen; while still holding the wheel down. I'm sorry if this doesn't help or doesn't work. But it worked for me!
