the Range object in IE and the Range object in Mozilla are fundamentally different (ref.) you need to use/develop a cross-browser version for your code.

Get rid of the bold tags in the middle of your javascript call, look before the function:
<a href="javascript<b></b>:createTag('b','txtA')"><strong>B</strong></a>

To simplify the inter-browser compatibility, use jquery and let the API do the work of figuring out those different commands for you.
