Free space plus Used space does not equal capacity?

[weberlajes]

I've got everything up and running. I'm at 10.4.2 (no sound, but whatever, I'll deal with that later). But I'm trying to do the 10.4.3 update apparently only have 750MB left of diskspace. Even though Disk Utility tells me:

Anyone have any ideas about what I can do to actually use the space I should have?

Also, I've searched around and have come across a few other people who have this problem, but haven't seen any solutions yet. If they are out there and I've just been too dense to see them pointing me in the right direction would be just as appreciated.
