Under XP theming, the playlist switcher panel with a sunken frame uses the system window background colour in the window frame instead of the colour defined in Columns UI prefs (will not be fixed)
Cannot set a playlist filter for playlists beginning with spaces
If you have a vertical and a horizontal scrollbar in the playlist, there are painting problems in the little area that joins them.
Edit this column does not work properly if columns page is already up in prefs
Under XP theming, with broken visual styles, the status bar does not use the font specified in preferences in all parts, and is not sized correctly. The use of the incorrect font only occurs when a status bar font is specified in the theme you are using. (can/will not be fixed)
