You know the random chat text bug I mentioned? It's caused by pressing CTRL+@ (or CTRL+SHIFT+2) which is a control code that creates a character equal to 0. JJ2 has a function that returns a character from a queue, but it returns 0 when the queue is empty. When 't' is pressed to open up the chat field, JJ2 attempts to clear the queue (since no characters are removed from the queue when the chat field isn't visible) by calling the function until the return value is 0. But the function may return a character equaling 0 resulting in the queue not being cleared completely, and this causes the bug to appear. FawFul helped me to figure it out, and the next update will have the fix.
