CFFORM with flash format does not work in Internet Explorer ONLY

[siriusthird]

I am new to flash form in coldfusion. I tested a simple code in both Firebox and Internet Explorer.

- In Firebox, it works as expected.
- In Internet Explorer, nothing is displayed.

Appreciate if anyone could let me know why it likes that and how to solve it.

My simple code:

<cfform name="MyForm" format="flash" width="500" height="500">
        <cfinput type="text" name="MyText"/>
        <cfinput type="submit" name="MySubmit" value="Save">
</cfform>
