Hmmm.
Microsoft still haven't fixed a stupid but that means when you use a custom recycle bin icon it doesn't automatically change on deleting/emptying. You have to manually edit teh registry to put a ,0 at the end of the icon path*
*The Windows registry seems like a very strange place to me. There are so many entries that take extra bits like that, that don't seem to serve any purpose, but I'm guessing are left over from some planned functionality that was never implemented.
