Whenever I use print() or println(), any words showed in the message area become an error with each character turning into the one two letters before it. For example, if I type println("hello world"), it will end up showing "ebiil tloia". There are two letters "f,g" between "h" and "e"; there are also two letters "c,d" between "e" and "b", etc.
I have searched for a long time but found nothing... What should I do? Thanks in advance for any help.
