The title pretty much says it all.  I'm using Vista Home Premium and when I use the internal player for my deskscapes/dreamscapes, I'm not able to move my desktop icons.  Weird!

I've also found that choosing the different background video centering/resizing options don't seem to be functional unless I'm using the internal player.  When using the internal player, I can choose different options, deselect the internal player and the choices will persist, so there is a kind of workaround.
