At the time, earlier this year, it seemed that Adobe had suspended maintenance
of the 64 bit version of Flash. The update I had received at the time was thru
the repos. It probably depends on the graphic card. I guess I'll try the 64bit
install and see how it goes.

The good news is that while looking at videos today on youtube, one video
actually came in in html5! No Flash! signs of things to come!
