[MacRuby-devel] windowControllerDidLoadNib strangeness

[Laurent Sansonetti]

Hi Tom,

I just created a sample NSDocument-based project, and added a windowControllerDidLoadNib: method to the NSDocument class, calling super as you do, and everything worked as expected.

Could you try that and see if you still see the problem? Also, do you run a 32-bit machine?
