I was working on a Flash project .fla with some static and dynamic textfields using an embedded .otf font on a Windows machine of mine. Everything worked well and the compiled output swf looked great.
However, when I sent the .fla over to someone I was working with who was working on a Mac, the text in the .fla appeared about 10 to 20 pixels to high, and the compiled swf was incorrect in the same way. Note that we had the exact same .otf font files installed on our machines, so it's not that we had slightly different versions of the font or anything.
What causes this problem? How can it be fixed? Would any other info make this problem easier to diagnose?
