Ultimate the same thing can be seen with the windowsvista style, just not as pronounced. With the windowsvista the cell retains a dashed line.

With the windowsvista style I feel that it's more clearly noted that this is "where you last clicked" whereas the fusion style makes it seem like it's actually highlighted.
Is this behavior something that can be turned off?
