Important Notes about This Release

• Note: As a best practice, Citrix recommends that you install this and other hotfixes only if you are affected by the specific issues they resolve. Otherwise, Citrix recommends that you wait for the next hotfix rollup pack for your product release. Hotfix rollup packs consolidate most previously released hotfixes and allow you to update systems in a convenient, single installation.
• Important: Installing this hotfix over an ICA session is not supported but you can install it through a remote desktop session using an administrator account.
• Caution! This release may require you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

New Fixes in This Release

1. The winlogon.exe process might close unexpectedly on twi3.dll.

   [From XA600R02W2K8R2X64079][#LC2244]

Fixes from Replaced Hotfixes

1. Launching Internet Explorer in kiosk mode (iexplorer.exe -k) on servers with Fix #LA1588 installed causes the browser to run in maximized rather than full-screen mode.

   [From XA600R02W2K8R2X64003][#LA3131]

2. While launching an application, command line parameters are converted to lowercase regardless of the case specified in the application properties.

   [From XA600R02W2K8R2X64003][#LA3220]

3. When using the Connection Center or the Web Interface to log off from a seamless session with unsaved data, a black window appears with the following message:

   "Programs still need to close" - with the two options - "Force Logoff" or "Cancel." The "Cancel" option does not work.

   After installing this fix, the Cancel option works as designed. After utilizing the Cancel button, Citrix recommends that you save your data and then log out of the session to prevent further performance delays.

   [From XA600R02W2K8R2X64007][#LA0318]

4. When closing a XenApp session, logoff scripts might fail to get executed.

   [From XA600R02W2K8R2X64009][#LA3017]

5. When attempting to reconnect to a disconnected session that is locked, users might be prompted to reauthenticate. To enable this fix, you must set the following registry key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\WFShell
   Name: LockOnReconnect
   Type: REG_DWORD
   Data: <0=OFF; any other value=ON (default)>

   For related information, see Knowledge Center article CTX138189.

   [From XA600R02W2K8R2X64020][#LA3642]

6. On systems with Fix #LA0318 (Hotfix XA600R02W2K8R2X64007) installed, published instances of explorer.exe running in a seamless session become unresponsive when right-clicking to perform an action.

   [From XA600R02W2K8R2X64044][#LA3757]

7. When switching between local and published applications by using the mouse, the keyboard input might not work.

   [From XA600R02W2K8R2X64077][#LA5849]
