Since 10.8 (or was 10.7?) you can get yourself into a situation where you can’t select the last item in a column. Yes, that’s right, Apple’s updated UI is so awesome, and so perfect, that you can’t possibly need the last item in a list. Check out the snapshot below,
See that last item ‘XQuartz’? Because the bottom scroll bar appeared over it, I now have no way to select it. If I leave my mouse hovered over it, the bottom scroll bar never disappears and I have no way to select the item. You have to to either key down, or move the mouse away in a manner that causes the scroll bar to vanish, and then try again. It’s ridiculous.
Ironically, as I’m typing this post in MarsEdit, the same problem is presenting itself again. The magic appearing scrollbars are blocking out the bottom line of text in the post, which is exactly where I’m typing. It’s so awesome, that I’ll upload that as well,
The bottom line here is that this is completely unacceptable. Apple didn’t used to make this kind of stupid UI mistake, did they?
