Debugging console application - stdin redirected?

IDEA 6.05
I'm starting a project based upon the jline library for console input that will evenually yield a shell type program.

Problem is that IDEA doesn't recognise any input from the console - is stdin being redirected or do I have to do something special to configure this?

I could of course run the application from a command line and debug it remotely, but obviously that's a last resort.

Thanks
Steve
