http://forum.maxthon.com/index.php?s=c0 ... owforum=48It appears to be having a few teething problems. I couldn't work out from the web site whether it is wholly independent or a skin over the IE engine. This early in development reference suggests maybe the latter "Maxthon (MyIE2) 1.0.0168 beta".
One post on the forum suggests a connection with Favicons. I experimented with Favicons a year or so ago and it did install spyware into IE, and was a real b..... to get rid of, so I would be cautious.
