Hi,<br>
<br>
I'm using MS4W with Windows 7.<br>
When I call <a moz-do-not-send="true"

The "proxy.cgi" file was created in

"""This is a blind proxy that we use to get around browser<br>
restrictions that prevent the Javascript from loading
pages not on the<br>

it's less<br>
efficient, it might break some sites, and it's a security
risk because<br>
people can use this proxy to browse the web and possibly
do bad stuff<br>

I've modified "proxy.cgi" file at "allowedHosts" by adding

<p><small><small>I must modify the first row of "proxy.cgi" file?<br>
Can this issue related to the Windows 7 OS?</small></small><br>
