When I open my inventory and go to the search tab, I enter something in and everything goes wonky. I am done searching so I press backspace and the entire search term disappears. I enter the chat to say hi to my friend who just joined, I misspelled his name and I tried deleting the accidental character, and the entire name disappears. Say his name was George, and I type Goerge instead. I would press backspace, and all "Goerge" would disappear. (Get what I mean?) This happens until I completely re-start the game.

Delete whole word: CTRL is stuck, delete whole line: SHIFT is stuck.
