When moving the scene extent all data are refreshed from source using the new scene extent. If the new scene extent contains too many data GeoScene3D may run out of memory or even crash.

If “Enable Project Restore” is enabled the project is saved in a temporary backup file before attempting to move the scene extent. If the move scene extent is cancelled by the user or if GeoScene3D crashes the project can be restored from the saved backup. The project backup filename has a tilde prefix “~” and is automatically deleted unless GeoScene3D crashes.

Enabling project restore takes extra time though and should not be necessary for the experienced users.
