ALT+D moves the focus to Address bar in IE8

[MKohli]

Hi,

My application uses hotkey ALt+D to fire a link, but now in IE 8 when user press Alt+D then focus goes to address bar of IE.
I cannot change the hotkeys because that will take me to train the user again.
Is there any workaround for this?

<b>Application details:</b>
.Net framework 3.0
Language C#

Thanks in Advance!!!!!
