v.0.21(L) Next button doesn't inherit info from folder tree

[marsh]

In folder tree, switch back and forth between several different folders. You'll see the "Previous" button turn blue.
*The "Next" button remains inactive even while selecting same folders repeatedly in folder tree. It never becomes active unless the "Previous" button is used first.

Yes it's normal. Next button will be active only if you use Previous. It's the same in folder tree or thumbnail view
