AVRProjectIDE - Editor for AVR/Arduino Projects

I have started using your IDE but I have a slight problem which I am sure is me rather than the IDE.
I am rather new at AVR/Arduino .
I have got the project to compile and upload fine (it seems) but the serial.println() function now only prints memory addresses .
From the Arduino environment using the the same code this has not happened.
Any ideas ?

It really is a great IDE.

Thanks for all the hard work
