I'm using an Apple External Keyboard as well as the macbook's default keyboard with my pt-PT layout viewing the IronPython/Ruby Interactive Shell in http://ironpython.codeplex.com/Wiki/View.aspx?title=SilverlightInteractiveSession
Somehow it accepts my input as a en-US layout. For instance shift+0 (= in my layout) writes ) in the shell. Which is wrong.
Also, clicking the about link does nothing but making the SL canvas white. It should work also.
