This is a good question although it does not relate to language learning. I am using either IE8 or Google Chrome, and I experience the same problem when I am in this website! Fortunately, I almost never chat through here. I suggest that you may reflect the problem to the technical support team of italki. === Good day. / 祝 是日安好。

many peple use skype.

I have received a mail from Italki support team. Within few days they will solve the problem.

I agree with Mitong.
