regarding patching the Receiver.arf file, why not create a Windows utility that lets people drag and drop new files into the Receiver.arf file and have the utility create a new arf file with the new and/or updated files in it?

That would be good, but I don't have time to write such an app at the moment.

I can program in VB and could knock up such a program in a weekend - yes it would be something you'd distribute/let folks download and install themselves, but iot could keep backup copies of the .arf files before it updated them so you could go back.

That would be great if you or someone could write it.

I think arf files are basically compressed tar files? or similar?

They are not compressed, they are just plain tar files.

I'd send you an arf file to work on until you get your Receiver, but I'm not allowed to...
