tree expand icon en-clickable (uncached remote directory)
on remote folder tree.
when remote directory is uncached, folder icon is clickable to expand through natural (auto-expand option was enabled),
but tree expand icon is not clickable.
It's possible that maybe Windows Explorer uses some sort of special trick to do this, I am not aware of any way this can be done. If anyone happens to know i'd be more than happy to look into it.
