I used RubyInstaller to install Ruby on Windows 7 (32-bit). I have many gems installed, though I'm not able to run gem list (no output). In my scripts I use mechanize.

I get the following error when I start irb:

C:\>irb

I can run ruby as a service using System account (Redmine works fine on Thin). But when I try to run it from my account I get the following:

C:\www\redmine>ruby script/rails -e production -p 3000

Re-installation fixes the problem for a while. And I can't figure out what's causing the bug to reappear.
