Thanks for the replies guys (and sorry rj, I should have said MacBook Pro). AndyL, checking the Racelogic site, the latest Mac OS version is 1.3.6 (which I have) (v2 is the Windows flavour). It looks like I need to contact Racelogic as the first picture below is what the map should look like and the second one is a screen shot from one of my files. I can't access the track files as the VBox sport has them all built in - its a pure "plug and play" solution - just wish I could get it to play a bit better!
