I'm not running Vista, but happened upon this particular gaffe and thought it was worth sharing for those of you that use Vista or have users that do. The link also has instructions on restoring and stopping users from this particular problem.

I would have thought that using "Remove Recycle Bin" or even "Delete Recycle Bin" rather than "Delete" would have been a better option.
I guess that MS didn't pass round the "Don't make me think" book.
