Odd bin behavior when adding clip to bin (Beta)

So I have a bin full of MOV files showning in a window where the clip thumbnails are 4-wide and I have to scroll to get to the bottom.

If I add some music clips to the bin (drag/drop from Explorer window) these go to the top, but the bin scrolls to the bottom.  So far, no problem, bin is set to sort by label.

So I scroll up to get to the top, and it won't go!  It'll scroll up but when I let go of the mouse wheel, it scrolls back down. If I use the elevator bar, it does the same.  I can't select anything but what's at the bottom.

If f resize the bin so all the clips show, I can get to them. And if I then shrink the bin back down to 4-up, it works.  

It's an odd annoyance I've never seen before.
