Sometimes when I put text in my sprite's costumes, the text teleports to the upper left hand corner of the costume editor. Once I hit enter, that is. And it makes me mad sometimes because for every single costume I have with text, I have to go in and move it back to the spot where it was. I'm not sure if anyone else has this problem, or if it is only my computer, but please help if possible! Thanks!

That is actually a common bug.
