I'm great fan of airplanes. There is one website: www.passur.com, which gives in near real time the traffic over some of the US Airports. For example the link: www4.passur.com/jfk gives all the in-bound and outbound traffic to/from JFK airport. This page requires Java. I installed it and everything was OK. But from some time - 2-3 months - every time I try to open and watch the traffic there is message saying "application blocked" and in the message box is written - on the first line "Name: A"; on the second line "location: www4.passur.com"; on the third (last) line is written "your security settings have blocked an untrusted application from running"; and on the right bottom corner there is a button "OK". The question is how to unblock this and to view the webpage. Thanks in advance.
