Charles I had the same problem with a slide show I created a while back. The title page had both a background image & text, which was created in object editor, when viewed on my computer both the image & text were centered on screen as they should have been but when viewed on a friends computer only the image was centered, with the text both enlarged an overlapping onto the right hand side of the screen. I noticed that not only was the text enlarged & off centre, but it was also a different font from the one I had written the text with (Times N/R instead of the script font I had used). I assumed from this that maybe P2E doesn't embed the fonts within the presentation but looks for them on the host computer, I then changed the title font to a more universal font (Arial, I think)? and it cured the problem, In this instance anyway.
