New Fixes in This Release

This hotfix rollup pack introduces the following fixes that have not been previously released:

HDX MediaStream

1. With clear text logging enabled and the level set to 9, the PseudoContainer.exe process can exit unexpectedly.

   [From OnlinePlug-in_12.3.400][#LA3431]

Session/Connection

1. In a multi-monitor environment, the Desktop Viewer toolbar might no longer be visible while switching the display to a secondary monitor in full-screen mode.

   [From OnlinePlug-in_12.3.400][#LA3083]

2. With Taskbar Grouping enabled on the client device, TaskbarGrpXpVista.dll - within wfica32.exe - unnecessarily queries the client device for information about published applications running in the session. For example, when running a published instance of cmd.exe, TaskbarGrpXpVista.dll queries C:\windows\system32\cmd.exe for information about the executable. In scenarios where the published application is running from the remote share, this can cause undesirable bandwidth consumption.

   [From OnlinePlug-in_12.3.400][#LA3661]

System Exceptions

1. The wfcrun.exe process can exit unexpectedly in environments where HP LoadRunner is deployed.

   [From OnlinePlug-in_12.3.400][#LA0859]

2. The wfica32.exe process can exit unexpectedly when using an auto-configured proxy connection.

   [From OnlinePlug-in_12.3.400][#LA1712]

3. The wfcrun.exe process can exit unexpectedly in environments where HP LoadRunner is deployed.

   [From OnlinePlug-in_12.3.400][#LA1774]
