I updated Minecraft, and found out that I can only type in chat when the keyboard sign is showing (I have to click on the arrow next to the send button). Not only that, I can't type normally on signs or edit on anvils at all (unless I restart my computer, which is VERY annoying)! And what's more, one of my friends can't type normally (same as me), one of my friends has to restart her computer in order to type, and the rest of the friends I play with CAN type normally! Can someone help?
