New Fixes in This Release

1. With compatibility view enabled in Microsoft Internet Explorer, certain third-party websites with Flash content might not work.

   [From ICAWS760WX86048][#LC7513]

Fixes from Replaced Hotfixes

1. Internet Explorer might close unexpectedly when attempting to play a video in web sites where:

   • The option "Disable Flash acceleration" is enabled or if the site is blacklisted.
   • The user is using a Receiver version that does not support Flash redirection such as Receivers for Mac OS X, iPad, iPhone, and Android.

   [From ICAWS760WX86016][#LC2256]

2. Flash redirection fails for videos embedded on m.mlb.com and msn.com. A black rectangle appears in place of the video.

   To enable this fix, set the following registry keys:

   For mlb.com:

   HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\HdxMediaStreamForFlash\Server\PseudoServer\ASJSCallbacks
   Name: m.mlb.com
   Type: REG_MULTI_SZ
   Data: <place each value on a separate line, null separated>
   setPlaylist
   startPlaylist

   For msn.com:

   HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\HdxMediaStreamForFlash\Server\PseudoServer\ASJSCallbacks
   Name: msn.com
   Type: REG_MULTI_SZ
   Data:<place each value on a separate line, null separated>
   MsnVideoCallback
   MsnVideoPropertyCallback
   GetWidgetID

   This fix works only for Internet Explorer 9 and later. To allow this to work, set Internet Explorer to run in emulation mode and set Internet Explorer versions 9 and 10 to document mode. For more information, see article CTX136588 on the Citrix Support site.
