title: Silverlight crashes FireFox 3.5, IE7, & IE8
body: <p>One of my users has an HP Pavilion DV4-1430us laptop running Windows Vista Professional 64-bit. She is using the latest version of the Silverlight Plug-In, downloaded on 24 July from microsoft.com/silverlight.</p>
  <p>While typing in a text box in a silverlight web application my company developed, all three browsers will occasionally crash. Nine times out of ten, she can go back to the page where the crash occurred and pick up from where she left off, only to have it crash again several minutes later.</p>
  <p>This only occurs while she is typing in a text box, and it only occurs on her laptop. I have watched her to confirm there is no user error.</p>
  <p>Any thoughts?</p>
  <p>Edit 1: I replicated the error. In Firefox 3.5, the window in which I was working closed with no warning, and the Mozilla Crash Reporter popped up. I'm pasting the crash report code:</p>

  <p>Edit 2: I replicated the error in IE8. I highlighted the text in a text box and began to type. Instantly,</p>
