I know this area of code was recently fixed for IE8 issues, but
something else is going wacky.
line 1065 and 1002
elem[ name ] = value;
change this to
try{elem[ name ] = value;} catch (err){};
and you're avoid errors being thrown in IE7 when a property is send an
invalid number.
You should of course be making sure to pass valid information, but in
my case, there was a plugin sending bad information. This also makes
IE7 behave the same way as Firefox and Safari, for more consistancy.
A bug report has been filed, but this will fix it right away if need
be.
