[MacRuby-devel] windowControllerDidLoadNib strangeness

[Thibault Martin-Lagardette]

Hi Tom,

I can't seem to understand what is wrong, I guess, since you said everything else works, that you did call the necessary `framework "Foundation"`?
Could you maybe provide us some test project, so that we can reproduce and maybe trace the error better? :-)

Thank you!
