In general it is working fine. There are however a few bugs. A search of the forum should link you to the topics. They seem to be mainly text handling issues.
There is just one thing to precise. All the font used in this exemple on AC9 or AC10 Mac/PPC take the capitral letter as reference for the 10mm size exept the MetaCorr ???
Here is the same file creted on AC9 Mac/PPC but opened with AC9 on Mac/Intel. There is a problem with the MetaCorr font who seems to take (approximatively) the capital letter for the 10mm size !!!
Always the same file creted with AC9 on Mac/PPC but opened with AC10 on Mac/Intel. We can see with the green mark the difference with the fonts sizes...
