Currently using version 22.214.171.124
While I was diffing a folder, and viewing in tree view, I open a folder to view children. After seeing them I decide I don't want the whole folder. Without closing it back I right-click on the folder and delete (in this case only deleting right, as the items are right side only). icons for children remain, sometimes name goes away, but not always. Click on child's ghost and attempt to delete it cause I haven't had enough sleep and I'm thinking I must have done something wrong, delete box comes up showing that entire C:\ is being deleted.
Not sure how bad this could have gone as I canceled immediately. But I'm thinking it might be better if winMerge would remove those children's ghosts when I delete the containing parent.
