Flash is one of the worst programs out there and that is made worse by the fact that more and more web developers cram as much of it into a site as possible. There is a very good reason why one of the most used add-ons for any browser is to block flash content. It uses too much resourses, crashes he browser window too often and regularly stays an active process long after the browser is closed and has to be terminated manually. At least on my 64 bit Windows it does. I am even trying the GPU accelerated beta version since I have an SLi /quad core and it still runs like crap. Adobe is without a doubt one of the laziest companies out there and Flash has one of the worst security records going.
