Don't blame it on the lizard. The gecko engine itself works fine (it's what moz, firebird/fox, k-meleon, netscape, konqueror, beonex, and most other browsers use), it's just myie2's implementation that's buggy. Most likely it's due to the active-x aspect, or perhaps a conflict between the active-x component and your security settings.
If you want to see how the gecko engine performs in a proper application, tryout K-meleon
http://kmeleon.sourceforge.net/download.php It's only about 5megs.
