When I watch the fullscreen video on this site and it ends, instead of continuing to the next part (you can see there are 3 parts of this video), I get this error:
Microsoft Visual C++ Runtime Library
---------------------------
Runtime Error!
Program: C:\WIND...
R6025
- pure virtual function call
It happens only in Firefox (version 26) and using the newest Flash 11.9 or even 12 beta. I remember it's been like this for a few months (older flash and firefox versions too). When I'm not in the fullscreen mode or use Chrome everything is OK.
