Strange IRB problem

strange.... I'm on Vista and updated to Rails 2.2.2 and rubygems 1.3.1 with the usual problem there. ...but fixed that pretty easily ..(it's well documented)...

everything was fine....but then I tried to use IRB. in every shell I have (netbeans, git bash, windows shell) I got this result:

What version of Ruby are you running? From the output, it appears that somebody's commented out several DOS batch commands (@echo and friends) with #s in irb.bat.

Does calling irb directly from the command line work?
