Issue
TGML graphics Editor will not open even though the Engineering Dongle is connected.
Environment
TGML Graphics editor
Vista IV
Cause
The Vista IV engineering Dongle is not licensed to allow TGML Graphics Editor to open. It will only allow OGC Graphics Editor to open. This Feature was not included until Vista 5.
Resolution
Use a Vista 5 Engineering Dongle or download the Demo License to edit TGML files.
