You may have clicked some externals links that launched your default browser of Safari. To get around that, just open Safari's preferences -> General and set the Default web browser to Webkit.
Good thought; thanks.
I think, though, that I'll stick with Safari for the time being; WebKit's RAM usage didn't appear to have improved all that much, and my browsing habits make it a "no-hassle" to quit Safari periodically.
And, in a different vein, I know myself, and I don't want to get (neurotically, as I do) involved with anything that changes nightly unless it's an absolute necessity.
