RadMaskedTextBox weird behavior in IE7

[Richard Nash]

My user's are restricted to using IE7, and the RadMaskedTextBox is behaving very weird in this browser.  When focused on the control, the insertion point moves to the end of the masked characters when a button is pressed.  For example, if my mask is "(###) ### - ###", and the insertion point is at the beginning and I press "1", then the text displayed in the box becomes "(1##) ### - ###" and the insertion point moves to the very end and no more text is able to be typed in.  Now if I move the insertion point with the mouse cursor to the proper place after the "1", then I can type the next character but only to get booted back to the end of the mask all over again.

Here is my markup:

<telerik:RadMaskedTextBox ID="rmt_Phone_Number" runat="server"
      Mask="(###) ### - ####" PromptChar="#" HideOnBlur="true">
</telerik:RadMaskedTextBox>
