[Oberon] PO2013 - System.CloseTrack / System.ExtendDisplay

The handling of multiple screens/desktops is a function of the OS.
If ETHO - being a complete OS - should support multiple screens/desktops we would have to implement this multiscreen functionality in ETHO. This is not done yet. If so, the frames with the same name will be fully synconized even if on different screens.

However your described setup is totally different: You start three different ETHO instances on top of a Linux OS. So you run three different Guest OSes (namely ETHO) on top another Host OS (namely Linux). This is called virtualization.
In this setup you can not expect that the GuestOSes syncronize files.
