Flash Plugin not being recognised for some websites
When the time comes to update your Flash plugin and yours suddenly stops working you might want to take a quick look at http://www.jasondunn.com/vista-flash-problem-youtube-250 . I had updated my plugin to 9,0,124,0 and got confirmation that everything installed OK, however after doing a bit of surfing it quickly became apparent that this was not the case. I followed the guidance provided by Jason and the plugin is functioning normally again.
