Web client not receiving any data?

Yes
and I could see "onStart" working, both with 1275 and with the current library version.
For a further check, please ensure that the code in your lspushpage.js starts with:

var LS_pushpageSrcRev=" 405 $";

My lspushpage.js does start with that, but the code in that javascript source file makes no reference to onStart. I recently downloaded from your website a new Lightstreamer.zip file and the lspushpage.js in there starts with:

var LS_pushpageSrcRev=" 481 $";

And this sourcecode DOES contain references to an onStart property of the Table() object and will call the function associated with it. I therefore conclude that my original javascript simply doesn't support onStart. I haven't switched over to the newer version and tried it yet.
