Popup blocker warning when starting Lightstreamer connection

[kpturner]

When I start Lightstreamer on an application via a host that I have not previously used, I get a popup warning from my browser (Firefox). If I don't allow the popup, it doesn't prevent the LS from working which is good. However, it is a bit annoying to get the warning. If I take the option to allow the popup then of course the warning goes away, but you still see a small pop-up window appear very briefly at the top left hand side of the browser window.

Can you tell me if this is expected behaviour, and whether or not it can be suppressed?


EDIT: I think this belongs on one of the JavaScript Client sub-forums - sorry
