Build and run not working in osx lion.

[Calexus]

In osx lion the build and run command doesn't work. I only get a command printed in the Build Log but no terminal is opened. If I copy paste the command and run it manually it executes my application in an new terminal as expected. Have I done something stupid or is it broken in lion? This is a fresh installation, not trunk, and a project generated from the console application template.
