Hi,
please, could you tell me which client library are you using?
I confirm that on our development version (the one used for the demo of
www.lightstreamer.com) such javascript:void(0); call let the engine disappear, but for the last distributed version (the one used for the demo on
http://push.lightstreamer.com ) only the connection is dropped.
Did you observe something different?
Btw everything is related to this known issue:

please let me know if that solves your problems
