Hello all,

A novice working with LightStreamer. We are running an older release (Presto 4.0.2) and I'm working with the JavaScript Examples and various client libraries.

It looks like I can use the JS 5.0 client library, but all demos that us the JS 6.0 client library fail (such as Jgrid_Demo).

Is the requirement for using the JavaScript 6.0 library a certain version of LightStreamer on the server (something newer than Presto)?
