Mac Help doesn't work

Is this Leopard or Tiger?

Was it working at one time, and recently stopped? ...and have you tried simple troubleshooting steps like restarting?

 

I assume Leopard as I am having similar issues with the help system myself. Links don't work in the help centre at all for me. I have no idea what is going on. I installed Leopard on a completely formatted disk so it should be absolutely clean. The only other thing I have installed is iWork '08 and Logic Studio 8.

 

This just happened to me when I was looking up help on Time Machine. I would click on the links within the help menu of Time Machine and nothing would happen. When I started it all over all was well.

 

Funny, Leopard Help works perfectly for me (and much better than Leopard's ever did, I might add).
