Macromedia released an update for Flash Remoting yesterday which fixes quite a few issues. The update is not for the version of Flash Remoting that comes with JRun or ColdFusion — it is only for .NET and Java. The Flash Remoting updates for ColdFusion will be contained in the next updater. Remember that you will need to download the Flash Remoting UI components separately. I will post here the very moment they become available.
