Using MC 4.4 portable in Vista hm prem x64.
As best I can tell - looking at the MC Explorer Panel Settings, under File & Folder state colors,
the color & text style selected (default values for me) for both "files" & "folders" are identical.
When using both a tree column & file column - in ONE of MC's panes (usually R), only selected file names change the background color & text color (to blue background, white text).
Selected folder names in the folder tree (in same MC right pane as file list) do become bold when selected, but the selection box or folder name doesn't change color. The settings in MC seem to indicate that they would change colors.
MC also has a color selected by default for "FocusRect color" - also checked - but no files or folders in R or L pane change color with focus (hover) .
In Explorer, background changes color for selected items in both R & L panes, as do focused items.
Now, if I display only the folder tree in MC's left pane (no files), selecting the folder changes the background to blue & text to white. But it still doesn't show any focus color.
