[MacRuby-devel] NSTimer

[Robert Rice]

Thanks John::

I wasn't familiar with this new syntax. I was using the old syntax  
"NSTimer.scheduledTimerWithTimeInterval_target_selector_userInfo_repeats 
" but I see it doesn't work in MacRuby.

MarRuby is giving me error messages without a traceback. Is there a  
way to enable tracebacks?
