Why doesn't DO open folder from Open Containing Folder from uTorrent?

in uTorrent there's a context menu option 'Open Containing Folder'. When I use it, I expect focus to switch to DO and one of the panes has that folder open. This used to work and it stopped working.

Try turning Explorer Replacement off and on again. If it still doesn't work it's probable that uTorrent has changed how they're opening the folder.

It works better now. If the folder doesn't exist, file explorer opens instead. Is this how it's supposed to work?

Not sure.
