Hello, Lately I am getting the above error message whenever I am on the Internet. Can anyone help me how to overcome this problem?

Thank you for your help!

It sounds to me like you have the Flash Player Debugger installed in your browser. Try uninstalling your current Flash Player and getting a new install from get.adobe.com/flashplayer

I have done exactly as suggested and at least until now it seem to have done the trick! Thank you so much for your help - I am always in awe what people like you know and can conclude from an error message. Thanks again! Peter
