Rich Text Box compressing

[Gawdzira]

I have not seen this since about version x9. I am setting text with Rich Text and when I reopen the file my text is not displaying properly. See image for a typical example. I am not sure if this may be due to jumping between computers with different settings? I have been using 3 different computers over the past few weeks when I started to see this a lot. Is there a particular setting which will help me keep the text from doing this crazy dance?
