Hello everyone!

I`ve been working on this flash project for a while now and it’s kind of a 2 parter: the flash client and the server. The server and client are two completely different servers.  
I’m now trying to release a online demo version of the project but i had encountered a problem.

Being **server - client app.** , of course, there would be security sandbox limitations. But i took all the necessary precautions - a crossdomain.xml with this in it:

```php
<?xml version="1.0"?>
<cross-domain-policy>
  <allow-access-from domain="*" />
</cross-domain-policy>

```

(I got frustrated and put it everywhere on the server.)

- AND a [COLOR=“Blue”]System.security.allowDomain([COLOR=“DimGray”]"\*"[/COLOR]);[/COLOR]

**The result**  
Well I usually test my sites in Firefox and that’s the end of it. This **did not** work in firefox. Out of curiosity I tested this in Internet Explorer and it seemed to work fine.  
Firefox freezes when it’s supposed to load the first xml off the server. For debugging reasons I put in a bit of code which tells me what type of sandbox is running.

In Firefox this returns:\*\*\* remote\*\*\*. I don’t get to see what it says in IE.

**Summary**  
Firefox is not responding to [COLOR=“Red”]crossdomain.xml[/COLOR].

If you’ve encountered this or have any clue as to why this is happening please, please give me a shout!  
Many Thanks!
