4.2 upgrade information

You MUST have previously installed version 4.01 (4.0.3737). You can download the 4.01 upgrade from http://www.davevollmer.com/rcv401update.exebefore installing the 4.2 upgrade.The 4.2 upgrade is simply a replacement executable in a zip file. All you have to do, is download it, and unzip it INTO the current Radar Contact directory (by default, rcv4)If your Radar Contact default directory is on a different drive than the "boot" drive (the drive where windows is installed), you will need to request a new key by emailing [email protected] AFTER the 4.2 upgrade is applied. Sorry for the inconvenience.4.2 fixes what some people experienced after the 4.01 upgrade, stutters as I build the sound file to play. Even if you didn't experience stutters after the 4.01 upgrade, you should still install 4.24.2 also includes fixes for the following: a bug in the emergency vectoring code, if you were almost above the airport you decided to divert to using the great circle calculations to determine if you off course when the checkpoints are FAR apart when you missed a crossing restriction, and progressed a checkpoint,the heading watchdog gave you the wrong heading to fly once and for all, the interpretation of "resume own navigation" will be put to rest.
