Ok, don't buy it, it's working just the same. :) Mike

You don't say what your 10.6 freezing issues were (what were you doing when this happens? Are you getting the kernel panic screen? Or is it just freezing? Is it a total freeze, or is the mouse pointer still moveable, for example?), but have you phoned Apple and talked to an AppleCare tech? You get free tech support over the phone for 90 days or if the problem originates from the initial 90 days (though you may have a hard time convincing the techs of that, if you didn't phone and report it before the 90 days expires). You also have a year's free tech support at an Apple Store or Apple certified support centre, if one is nearby. If you're unsure just phone Apple and ask - they'll be happy to guide you to the nearest. FYI - most kernel panics are caused by bad RAM. Try running a hardware test <http://support.apple.com/kb/HT1509>). It _may_ reveal bad hardware. But understand it's not 100% reliable. However if it does show a problem Apple will have no problem immediately replacing the defective part or entire Mac - whichever they consider easiest. Apple techs can run more comprehensive tests, so don't trust a Hardware Test clean bill of health if the freezes persist in 10.6. I'd also say again 10.5 is NOT supported on your Mac model. I'm actually quite surprised it would even install. I've also found 10.6 more stable than 10.5. I think the vast majority of my Mac compatriots would agree on that point. So I'd suspect you have a hardware problem and need to contact Apple. They will likely suggest you reinstall 10.6 first, BTW, because they won't trust it's a persistent issue in unsupported 10.5.
