Do you mean each letter is below the previous one? If so then disregard everything in this post!
If you are new to Corel (I am only at version 12) it could be that you are making the mistake of selecting the Text tool which is meant for typing something, starting at the point you selected with the mouse.
Assuming nothing basic has changed with X3 then type the text as normal (left to right)
Then using the arrow (select) to click anywhere on the text, you should be able to Edit, Format, or Rotate etc. the block of text which has been selected.
