Known Issues
Android : Continue to look for JDK if JAVA_HOME points to too old JDK
Graphics : Shader error when building and playing Bootcamp project on Windows XP.
Scripting : Double-clicking a C# script will open MonoDevelop instead of Visual Studio.
If Visual Studio is already open with another project, it will still fail. However, it will work when Visual Studio is closed.
