I don't know how I got into this state, but the Xcode documentation window has been exhibiting this strange behavior of "jumping to top" whenever I hover over a link in one of the doc files.
For example, I'll be scrolling down to, say, the methods of a Class Reference, and as soon as I hover over one of them, the doc window jumps right back to the top.
Has anyone else encountered this? If so, is there a fix for within Xcode?
Meanwhile, opening up the doc in a browser works around the problem.
