[resolved] Calling IE's Save As dialog box

[solitario]

Hello all.
I have a function which calls the Save As dialog box in Internet Explorer. However, I have this on a PHP page and when the dialog box appears, the default File name comes with the *.php extention. Is there any way I can tell the dialog box to display it with an *.htm extension?

Many thanks.

<script>
function SavePage(){document.execCommand("SaveAs");}
</script>

<a href="javascript:SavePage();">
