I have the 64 bit version working fine on my own F15 machine, using
the free software amd driver, while I cannot get it working on my wife
and son's iMac 27 inch machines, each running F15, using the
proprietary amd driver, since the free driver doesn't work on these
displays.  I have tried it with and without the wrapper, both the 32
and 64-bit versions, and have run mozilla-plugin-config -i
/usr/lib64/mozilla/plugins/libflashplayer.so when using the 64-bit
wrapper.  It worked fine till about a week and a half ago.

The strange thing is that about:plugins shows each configuration
apparently working fine in each combination, and a visit to
http://www.adobe.com/software/flash/about/ has Adobe proclaiming that
the plugin is successfully installed: "You have version 11.0.152
installed".  But attempts to view Youtube videos cause the browser to
freeze.  This is a big use-case for my wife and son!

Is there an incompatibility between the proprietary amd driver and
version 11 flash?

Any suggestions on how to debug this?
