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. Using the CTRL+mouse left button to open a hyperlink in a new tab cause the new tab to not open for up to four seconds.

   To enable the fix, you must set the following registry key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI\
   Name: AAHookFlags
   Type: REG_DWORD
   Value: 1

   [From XAE500R01W2K8X64086][#LA2828]

Fixes from Replaced Hotfixes

1. With Excelhook enabled, the setting "Show all windows in the Taskbar" in Microsoft Excel 2010 does not take effect.

   [From XAE500R01W2K8X64069][#LA2225]

2. With ExcelHook and SpeedScreen Latency Reduction enabled (as described in Knowledge Center article CTX344154) in a fixed size published desktop, two Windows Taskbar icons appear per Microsoft Excel spreadsheet instead of just one.

   To enable this fix, you must create the following registry key:

   • On 32-bit Windows:

     HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ExcelHook
     Name: DisableInDesktopSession
     Type: REG_DWORD
     Data: 1

   • On 64-bit Windows:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432node\Citrix\ExcelHook
     Name: DisableInDesktopSession
     Type: REG_DWORD
     Data: 1

   [From XAE500R01W2K8X64070][#LA1253]

3. The previous implementation of Excelhook, which is used to create separate taskbar icons for each Microsoft Excel workbook, does not work for Excel 2010. This fix enables Excelhook for Excel 2010 if the following registry key is set:

   • On 32-bit Windows:

     HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ExcelHook
     Name: Enabled
     Type: REG_DWORD
     Data: 1

   • On 64-bit Windows:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ExcelHook
     Name: Enabled
     Type: REG_DWORD
     Data: 1
