When I test my .swf in Flash and load it with my Flash Player, the Alert box will appear. When I transfer the file to my server and view the web page in my browser, lastest and greatest of Mozilla Firefox, the Alert box doesn't appear. In the actionscript I have the import mx.controls.alert line, and I have transfered the Alert.as file to the relative folder of the server. I'm running IIS 6.0 in Windows Small Business Server 2003 on the server. Any Ideas?
