Unity Web Player Security Exception

Hi there,

I'm trying to run my game, which contains some networking code, in the web player under Safari. Safari crashes instantly, and I get the following message in the console log:

** (process:1923): WARNING **: The following assembly referenced from data-0x19a4200 could not be loaded:

The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (/private/tmp/UnityWebPluginInstance-695719292ad41c6d27a7f80840317cef/Data).



I looked in /Library/Internet Plugins/Unity Player.plugin/Contents/Framework/Mono1.1.0.bundle/Contents/Resources

and there is no System.dll.

I spoke to some kind people on #otee-unity, and one person had a System.dll, and one did not.

If System.dll is present, the browser still crashes, this time producing security exceptions.

Does the web player allow for socket calls? What am I doing wrong?
