  while (!Serial); // wait for serial port to connect. Needed for native USB port only

}

I have many sketches that compile and run just fine with this setup.

But when I try to compile the getting started example from RemoteXY I get the following compile error(s):

In file included from C:\Users\rayb1\Documents\Arduino\RemoteXY\RemoteXY.ino:28:0:

C:\Users\rayb1\Documents\Arduino\RemoteXY\RemoteXY.ino: In function 'void setup()':

C:\Users\rayb1\Documents\Arduino\libraries\RemoteXY\src/RemoteXY.h:153:77: error: 'RemoteXY' was not declared in this scope

I'm literally using the RemoteXY getting started example as is.

Any help is greatly appreciated!
