From the look of the questions and answers here Yahoo has done something that makes it impossible for some to rate answers or to submit an answer. For me here in the Middle East, this is the case. There is no longer any "submit" button nor can I find any other way to add my answer or rating. Nice job, Yahoo, of censorship!

There seems to be quite a few users unable to submit an answer.
I have found when it seems to decide not to work refreshing the page does help.
Rating seems very slow as well but once again refreshing pushes it through.
I suspect with the most recent changes Yahoo is having a few hiccups that hopefully will be resolved.

I'm fine with everything, Eastern US. The times I can't submit an answer were when the question had been deleted. Even deleted WHILE I was writing my answer!

Try refreshing the page pus f5 or push Control+ or Control-. also if you're getting a lower pop up asking if you want to show all content click yes.

Its a temporary glitch, hope it will go away.
