text problems

I've looked it up in Memories but it's not there. I don't think anyone's experienced it but me. =/

Before this 'error' happened, the text would freely go beyond the text border whenever I typed or pasted anything long. Unlike now, it goes back to the beginning and goes over the previously typed words/letters. Then at some point, it goes beyond the border and goes completely effed up. Sorry for the language but GRR... O__O Also, I can't move to the next line anymore. When I press ENTER, nothing happens. -_- Again, the typed letters go back to the beginning of the sentence.

This is really frustrating. I'm just about fed up with Photoshop. >__>'

Can anyone help me with this please?
