Do the widgets use animation? If so this might be an issue with ClearType. See:

You text looks fine to me in FF, IE7,8 and 9. Have you checked on a different computer?
@calex3710 – No animation, but thanks for the link!
@kmessinger – I’ve checked it on two different computers at two different locations. I’ll check it on a few more, and send the link to a few more people to see if they’re seeing the blur, too. Thanks for letting me know it looks OK to you!
