Font Size Changing between two computers

Hi,

Not sure if this has been asked before. Sorry if I missed a similar post.

Has anyone had trouble with the font changing size in storyline when you share a file with another person with Storyline. My coworker and I often pass Storyline course source files back and forth, but when she opens the course the font size is larger. Does anyone know if this is a computer or Storyline setting that we could adjust?

Thanks!
