Hi Youssef--

The problem is that there was no Sorcerer actively serving from the control system when the working system started (so the Apprentice in the working system couldn't connect to it). As a result, no message-sending connection was established between the two systems, so the proxy you were trying to use in the control system was nil.

The steps for operation are:

1. Start the control system and evaluate "self close; reopen" in the Sorcerer inspector. That will get it serving.

2. Start the working system (it will connect).

3. Check the connection by selecting "self" in the fields pane of the Sorcerer inspector. It should indicate that it has a peer connected to it.

4. You can then evaluate expressions that use proxies, like the "OtherBrowser" one.

'Sorry that wasn't clearer before.

thanks,
