Previously, I would click on a folder in the library pane (i.e. windows explorer's middle pane), and the folder contents, such as mp3 files, would show up in the preview pane. I could then select any file in the preview pane and play it.
After some updates yesterday, the preview pane no longer shows the folder content, but reads "no preview available". So now I have to double click on each folder in the library pane, which then shows the folder contents (such as individual mp3 files) in the library pane. I then select an mp3 file in the library pane, and now the preview pane shows the windows media player and I can play (preview) the file.
How do I get the preview pane to show the folder contents without me having to open the folder? I have preview pane enabled, "Always show icons, never thumbnails" unchecked, "Show preview handlers in preview pane" checked.
