First item
Why when I ask for a printed graphic software Macdive, all the software freezes on the print page.
With any application, everything works. my printer is a Brother MFC-7820N multifunction.

Second question
The first time I open the software Macdive I can transfer my data from the computer Suunto Viper air, but the second time he did not see the dive computer on the same session, why.

Thank you
