1) What kind of freezing was LimeWire causing?

2) There is no options menu. And there is only one item in the tools menu. It's not that I have greyed out options, it's that there is only one option under there tools menu. Are you talking about the Mac OS X version of LW?

3) My computer is a "normal" computer. It's an iMac. Certainly that's not as nice as G4, but it's a fine machine. I have no problems with anything other than LimeWire.
