New Fixes in This Release

Fixes from Replaced Hotfixes

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

   [From ICATS760WX64008][#LA5849]

2. When Session Lingering is enabled and an application is closed on an iOS or Android device, a black window appears and stays on the device screen.

   [From ICATS760WX64023][#LC1407]

3. When maximizing published versions of Excel or Internet Explorer, the top of the name box, formula bar, or menu bar appear as a white bar.

   To enable the fix for Excel and Internet Explorer, create the following registry keys:

   Excel

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI\XLMAIN

   Name: ClassName
   Type: REG_SZ
   Value: XLMAIN

   Name: Type
   Type: REG_DWORD
   Value: 0x00020000

   Internet Explorer

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI\IEFrame

   Name: ClassName
   Type: REG_SZ
   Value: IEFrame

   Name: Type
   Type: REG_DWORD
   Value: 0x00020000

   To apply this fix to multiple servers, create a registry flag. For more information, see "Seamless Per Application Window Registry Flags" in Seamless_Configuration.pdf on the Citrix Support site.

4. When opening a published version of Internet Explorer on Windows Phone 8.1, if the device is turned horizontally, half of the screen appears as a blank window. Additionally, users cannot maximize the Internet Explorer window. If users turn the device vertically, the screen appears normal.

   [From ICATS760WX64023][#LC2786]

5. A maximized published application window might cover the user device session's taskbar for session roaming from a device with a different display resolution.

   [From ICATS760WX64040][#LC3671]

6. Certain third-party published applications might fail to start on XenApp servers. As a result, the wfshell.exe process might close unexpectedly. When this error occurs, no indication that the session is starting or error messages appear on the user device.

   [From ICATS760WX64040][#LC3766]

7. Certain third-party published applications might fail to start on XenApp servers. As a result, the wfshell.exe process might close unexpectedly. When this error occurs, no indication that the session is starting or error messages appear on the user device.

   [From ICATS760WX64040][#LC3841]

8. In a seamless session, attempts to dock a seamless toolbar in a second monitor always results in docking on the primary monitor when the seamless flag for published toolbars is set to ON. For more information about the seamless flag, see Citrix article CTX101644.

   [From ICATS760WX64041][#LC1599]

9. In a multi-monitor environment, the application might open behind the published seamless toolbar application.

   [From ICATS760WX64041][#LC1673]

10. After undocking the Thomson Reuters Eikon toolbar in a multiple monitor session, the space occupied by the toolbar is not reclaimed by the session.

    In monitor configurations where the primary monitor is not located in the top left corner of the array, you must also install Fix #LC1599, which is included in Receiver for Windows 4.4 and later.
