Just recently a problem has cropped up where the entire ribbon on one site is grayed out as if it were deactivated, but the buttons still function normally. This isn't a huge problem, but it's bothersome to the clients who don't realize they can still use the buttons despite their appearance. So far it looks like an IE10 issue, but I'm waiting on responses from other clients to compare different browser versions. FF20 seems to work fine.
Has anyone ever seen this before? I can't find any relevant results on Google.
