When you start the timeSensor LEGAL client app, you will be asked which server you want to connect to (see C1. How do I connect with the timeSensor LEGAL Server?) If you want to avoid this step, create a *.4dlink file shortcut directly to your 4D database. Then, just double-click on the shortcut to connect to the database.
This is a 4D feature and not a feature of timeSensor® LEGAL. Follow this link and scroll all the way down to read about this in the 4D user manual: http://www.4d.com/docs/CMG/CMG40983.HTM
