I ve had this problem for the last year but I cant find a way of fixing it. I m using the latest flash version. Its now the 32 bit one as I tried that to see if it worked better than the 64 bit one (it doesnt), I ve tried so many things, like disabling hardware acceleration, all sorts but nothing works, I m at the end of my tether. I Googled it and there are lots of posts I ve tried so many things I cant remember them all. Can anyone sort it ?
