IE 8 Beta 2 - Your last browsing session closed unexpectedly
Are you seeing something like this with IE 8 Beta 2? I have been getting this on and off and just realized when this occurs. If you are debugging a web based project (ASP.NET or Silverlight) from VS and then stop debugging from VS, the next time you open the browser, you will get this message. No harm done. You just select the "Go to your home page" option.
Interestingly, this doesn't occur if you are debugging, but instead of stopping debugging from VS, you directly close the browser window.
