I am having trouble using the window on the left side of the screen.  For reading the API and whatnot.  The material in that window runs off the bottom of the window, and there doesn't seem to be any scroll bar I can see.  How do I read the bottom part of this information?

I've attached a screen capture from firefox.  I also tried chrome, with same result.  I also probed around with the mouse to see if maybe the scroll bar was there but hard to see.  I never was able to make anything scroll.

I think I need to scroll.  If there's some other way, someone please explain it to me.
