Hi Mone,

Maybe I have miss something because the previous issue only happened on the same host architecture on our testing server. When I deploy it on the separate host architecture (different host of Lightstreamer server and web server), it works on both IE and Firefox browser.

the separate two server to two different host issue is solve, it happen because of the setDomain command missing, I left out this command line previously . Currently the issues are done but I will go through lot more testing again anyway.

Thanks a lot for all the information.
