Hello,

I’m planning to run ruby setup script from lots of testclasses (NUnit)  
so I need to hide the console window. But starting process from C# with  
rubyw only returns error.

Then I try this helloworld-like test:

> echo sleep(5) \> tst.rb  
> ruby tst.rb  
> (sleeps 5 secs)

> rubyw tst.rb  
> (terminates immediately)

Why no sleep with rubyw?

What should I do to hide console window? My OS is MS Server 2003

Thanks!
