Flash ActiveX control 20.0.0.267 plays white screens

After upgrading to Flash 20.0.0.267 the embedded ActiveX control in our Digital Signage application displays white screens when flash content is playing.

This is a CRITICAL problem.  Many of our clients automatically update Flash and this will keep our Digital Signage product from working at their facilities.

Flash does however seem to work directly in IE and also in the Flash Player.  It seems only to be a problem with the embedded control in a .NET application.

I will begin to gather more information

Thanks,

John
