http://kiro.me/textualizer/ not working with IE 8 or IE 9

[doug123]

As per subject - visiting http://kiro.me/textualizer/ with IE 8 or IE 9 does not display the text. Nothing appears!

I've tried a local code sample and am experiencing the same issue.

I am seeing this error in the IE developer toolbar: (in local environment as well as web-site)

SCRIPT16385: Not implemented
textualizer.js, line 184 character 29

Any ideas how to resolve?

Thank you.
