To enable this fix in its entirety, you must install both a client hotfix that contains Fix #LA1621 and:
Note: This fix also requires the corresponding language code pages to be installed on both the client and the server. The code pages are installed by default by the Windows operating system. For example, the Japanese distribution of Windows 7 installs the Japanese code pages by default. However, if you are using a URL with Japanese characters on an English distribution of Windows 7, the Japanese code pages must be installed explicitly. This applies to both the client and the server because the URLs are transferred from the client to the server when server-side content fetching is enabled.
[#LA1621]
Certain user interactions with Flash content, such as clicking buttons, can cause Pseudocontainer2.exe to exit unexpectedly.
[#LA1948]
Client-side content redirection can fail for certain types of Flash content and revert to server-side rendering, including cases where:
