When I open a page which requires Flash Player I get a message box indicating "Adobe Flash Player 11.4.r402 has stopped working", with the sub comment "Windows is checking for a solution to the problem."
I have uninstalled my flash player and reinstalled it, no luck. I have removed Firefox and reinstalled with the same problem. I have disabled Flash plugin, after which I try a live feed from BBC this web site informed me I required a plug in, as expected.
I don't have this problem with Internet Explorer.
The actual flash version installed is: 11.4.402.265.
