1. Because it says 'Designed for Unknown', the inf file does not contain any information which says if its for Windows XP, Vista, 7 or 8. It will work exactly the same if you ignore the yellow. 2. It's not a new feature, i just fixed a few issues with it. I will have a look though . UPDATE: The reason why those forms are transparent is because they was set at 80% opacity for some strange reason, correcting that now.
