Local folder tree bug

In the local folder treeview:
1) select a subitem of a folder (any folder)
2) collapse the parent item by clicking on [-]
3) the item collapse and expand immediately and the selection goes on the parent item

explorer.exe and the FTP's treeview don't have this bug.
Both last beta and last release have this bug.
