Having deleted Adobe Flash, as recommended on the Loose Rivets thread, I tried again and things have changed ... for the worse. Whereas, initially the
video commercial only popped-up on the Loose Rivets thread, it now happens on others
BUT, not all ! No commonality among those threads affected and it only happens on this forum
. I have no idea what to try next, and, incidentally, videos on the whole PPrune forum appear as a black rectangle still!!
