Fix [ruby: no such file to load -- ubygems (LoadError)] in E-TextEditor

Go to the cygwin bash prompt. If you don't know how to get there, use Start -> Run -> c:\cygwin\cygwin.bat.

Type:
echo unset RUBYOPT >> .bashrc

Type:
. .bashrc

Type:
irb

If you see:
irb(main):001:0>

Input Japanese with WATIR

One more tip. You better use
   $ie.text_field(:name,'txtPcode').value = 'KANJI'
instead of 
   $ie.text_field(:name,'txtPcode').set('KANJI') 

TextField#set method fails on japanese characters.
