Your co-workers are using XP too?

What is the output of the following?

set HOME
set USERPROFILE

Here, Windows 7:

C:\>ruby -v
ruby 1.8.6 (2010-02-04 patchlevel 398) [i386-mingw32]

C:\>irb
irb(main):001:0> Dir.pwd
=> "C:/"
irb(main):002:0> system "ruby C:/Users/Luis/Desktop/t.rb"
Current directory: C:/
=> true
irb(main):003:0> system "call ruby C:/Users/Luis/Desktop/t.rb"
Current directory: C:/
=> true
