I've had the issue on Firefox and IE. I can get to my messages just fine but when I click on the contact I have a message from, the message and contact disappear. If I create a new message and send it out, when the contact replies it doesn't show my sent message just their incoming message that I can't click on. I can't bring my phone into the building I work in so this is my only way to stay in contact. How do I fix it?
