Filtration problem with the browser Opera 12.16

The internet disappears when upload video file on a web-site, only when using browser Opera 12.16. At disconnected web shield such problem isn’t present.
With others to browsers of such problem isn’t present.

Hi,
thanks for the report. Could you please expand a little what is the problem?

What is the name of the web-site? Can we try it here? What exactly do you mean by “internet disappears” - opera not longer connects to the web, while other browsers can, or that a whole system is not able to connect/browse web sites until WebShield is stopped?

Thanks a lot,
Lukas.

Hi, lukor !
Web-site : www.odnoklassniki.ru , upload video file on odnoklassniki.ru .
At this moment the Internet disappears, doesn’t work in all browsers. As if the canal is filled, but network connection works.
