I have not used vista much at all (don't really care to) but I just bought a new PC, and want to wait until college classes begin and I have access to Technet again

So the weird problem I have involves UAC. I have configured an administrator password so it of course should ask for a password when ever you try to install, or modify something. Problem is it asks for a password but does not provide a place to type in one, and the ok button is grayed out. Down right weird!

Any ideas?
