Composing in OWA - edit box error

I'm using Win2k and IE6 -- When I try to compose a message, I get a red X (missing graphic ?!)in the edit box where I'd actually put the message text. It's been like this for a while, but now I actually NEEd it... help!

 

try going into the owa options and downloading or re-installing the latest version of the s/mime control. this worked for me in OWA 2003
