Hi. I'm using one-click-installer Ruby 1.8.2 (2004-11-06) on WinXP-SP1 and I think I have a bug in the String method #rjust irb(main):002:0\> "0".rjust( 2, "-" ) =\> " 0" irb(main):003:0\> "0".rjust( 2, "-", 22 ) ArgumentError: wrong number of arguments (3 for 2)         from (irb):3:in `rjust'         from (irb):3 irb(main):004:0\> It's expecting 2 parameters, but ignoring the padding argument and using spaces. Does anyone else see this? M > **···** > > -- > Matt Mower :: [http://matt.blogs.it/](http://matt.blogs.it/) ---
