[MacRuby-devel] Problem with a window controller

[J Silver]

Hi David,

Try NSLog instead of puts. Also you can override puts to #NSLog.

I have some production MacRuby code up at 
https://github.com/jsilverMDX/GlobalChat2/tree/master/globalchat%202%20OSX 
that's in the App Store.

Look here for an example of a working MacRuby app that uses IB and Sockets.

Try firing an action on seperate view controller and storing your 
information there. I don't use Window object for much except showing and 
hiding views.
