DU3 looks great in IE10. The lines are different. It's more crisp looking.
There is a version of IE10 inside the Start Menu (Metro Interface). DU3 is beautiful in the Metro Browser. The only problem is with spell check. It corrects misspellings fine. But once spell check is completed, a message pops up. Metro IE struggles with the pop up message. IE basically freezes. Eventually the message text will appear and I can clear it.
