Defense+ & Flash playback issue in latest Chrome

Chrome updated the other day to the new version with the latest integrated Flash version and since then when I try to view any flash material, static or video, it appears as a blank white spot on the page. Audio plays, but no video. Disabling Defense+ remedies the situation but I have no clue as to what is triggering it or how to solve it. Looking at available processes for chrome everything is trusted. No problems with IE or standalone Flash. Nothing running in the sandbox. Any ideas deeply appreciated!

Never mind… following a major lockup, forced shutdown and reboot it is working just fine. No idea…
