It seems whenever WITE plays a new sound effect it opens a new instance of it in my taskbar and leaves it open (I can open/adjust every single instance.)
E.g. when starting the game, clicking the mouse (and hearing the corresponding effect) opens it once - more clicking doesn't close add any more, though. Then, e.g. doing airfield bombardments opens it again. Movement, battles etc. all add to it. I noticed it when I alt-tabbed after my first turn in the Road to Minsk scenario (still learning the game) and found half my taskbar occupied by the Status bar. [X(]
This is what it looks like after opening a scenario, bombing an airfield, fighting a battle and moving a few units.

All those instances shut down propely when I close WITE. I see no ill effects from this weirdness, but it's kind of irritating. [;)]
