ALSO!!!! because i did download it, i've i've been looking at it, you should make the full recycle bin the same size as the empty one, on my win7 dock, it's so tiny you can't even see it and i have it set to normal settings for size. JUST AS A THOUGHT. anyway, maybe i'm stupid but i cant figure out how to make the two of them work together, you know?
Nice work. Only thing I'd change, if possible, is the ? blocks. Rather than have the other icon on top, have it so when you mouse over the icon, instead of magnifying it on the dock, the other icon pops up.
