For people wondering how well SeeYou works under Crossover Mac, I have been using this configuration for a couple of years. I use it daily to analyze my flights. I have not been able to download a flight from a data logger but my loggers use either a micro SD card or are the equivalent of mac compatible thumb drives so I have no problem getting the flight logs on my Mac. Also, I cannot get 3D replay to work. I have tried installing different graphical elements of windoze like Flash and DirectX with no joy. So, If I really need to use the 3D features or if I am downloading a flight for another pilot I will run SeeYou under Parallels which gives it full functionality but is much more of a pain than Crossover. I also use SeeYou/Crossover to print out my flights at the end of the season since SeeYou under Parallels has a lot of trouble printing but Crossover does it well. I sometimes have to quit and restart Crossover when printing a lot of flights but this is not much of a hassle compared to SeeYou/Parallels.
