Thank you for the attention.

Thanks for the video, it was helpful and I can replicate the issue now.

Yes, folders under pinned node.

No no... Really is the "Tree (folder)" option that i'am speaking off... in view elements options...
I made a vídeo for better understanding. I hope its helps. and thanks for the attention.

In resume, no matter in who pinned folder i enter, the list show on the "Tree Folder list" always shows the files from the first pinned folder i entered.

By "Pin Folder" you mean a folder under Pinned node?
Otherwise the "Tree (folders)" was suggested to behave similar like "Media Tree" i.e. if someone prefers to have "Media Tree" hidden, but having an alternative when browsing folders. Maybe you are looking rather for something like "List (folders)" element -- that shows only the sub-folders of the curently selected folder?

I really loved the addition of "Tree (Folders)" on "View Element" but it has a problem...
Wen activated and i enter in a "Pin Folder" the player creates the list on the "Tree (Folders)" window and show it normally but wen i switch to another "Pin Folder" the list on the "Tree (Folders)" window doesn't change, continuing to show the same list as i entered first.

I am using version "5.0.0.2240" in portable mode but this problem is occurring in the last several releases.

Thanks for this wonderful program and sorry for any discrepancies in my english.
