@lynxster4 I'll look into it and get back to you.
Edit: so far I've found a bug when there's more than one consecutive spaces in the Text field. Is that the case for you? Otherwise could you please post which plugin settings you used? (Text, Fontsize, LetterSpacing, Text aligment, etc.)
Edit 2: OK, the bug seems to occur if the area of a line of text is to small (for example because the selection area is too small). This is now fixed. See the update in the opening post.
If anyone still experiences issues with the plugin, please don't hesitate to let me know.
