I grabbed nightly build 200707260000 (Basic bundle) and started with a new userdir. I opened testwww module in favorites window, opened attached file, and selected and copied all. I did New > Empty File, called it test.html, and pasted in the HTML. CPU hits the roof, have to kill the process. Doesn't happen when I paste into an existing HTML file. 100% reproducible on my machine.
