Hello,

I've tried to reproduce the issue but I wasn't able to do so.
In the case that IE6 even if is showing "internet" on the status bar is behaving like "local intranet", can you check these demos?
http://app.lightstreamer.com/StockListDemoQ <-WC 4.0.8
http://app.lightstreamer.com/StockListDemo <- WC 4.3 alpha2
http://app.lightstreamer.com/WC3_StockListDemo <- WC 3

Do you see the issue there?
The Active X behavior should not affect our library because we have some fallback so that the library should work correctly without them.

Do you have a publicly available PoC showing the issue that I can see?
We'd like to understand the issue even if it is related to old client versions.

Thank you.
