There is a new version of adobe flash 18 and something ( the version from last week was 17 and something)

It seems that the problem is with the add not the flash player.
With just one page of flyertalk loaded and one flash add ( it is like yourtube video, but play over and over again). Load my pc with 200 MB and 12% of the of the cpu power, this is just the load of the adobe flash player + what the browser load.

My pc is with i5 2,5 Ghz and 8 GB of ram so 12% cpu load and 200 MB is a lot.
