IE and unspecified error and in IE8 object doesn't support method
<p>I have a big (probably) javascript problem.</p>

<p>i have a long and complex script on the page based on mootools framework,
in FF and other browser everything works fine, but in ie 6 and 7 i got "error:153 (sometimes 84) Unspecified error" and the strange thing is in IE8 that show me the error "Object doesn't support this property or method".</p>

<p>someone know the possible cause of the problem? o maybe someone know a list of IE's unsupported property or method?</p>
