Receiver 4.8 and Alt+Enter in Excel Seamless

[Gestion Licences]

We have a bug with Receiver 4.8, doing Alt+Enter in a seamless session on Windows 2012R2 or Windows 2016 crashes the Receiver and we have to reconnect to the session. Sometimes, the application window turns black but most of the times Receiver crashes.
 

Alt-Enter is use in Excel to add a line break in a cell.
 

We don’t have this bug when we use a seamless session on Windows 2008R2.
 

Receiver 4.7 works fine with all Windows Server version.
Any hints?
Thanks

Hi All

 

The issue where Receiver 4.8 (Wfica32.exe) crashes when using combination Alt+Enter in a seamless session, is fixed now using a private LC8317. 

 

I would suggest you to open a Technical Support Case referring the private.

Same issue here with 4.8 and 4.9...

I'm seeing this bug in the year 2019 , using Receiver 14.9.0.2539 and Xenapp 7.15.3000 Server VDA. 

It does not seem to effect all installs though as i have another 14.9.0.2539 box and the key-combo works as expected. 

The user that fails to XA7.15 is however able to use Excel key-combo OK on conection to a legacy XA6.5 Farm. 

 

I plan to get the user receiver updated to 7.15.1000 or newer (which is should resolve as per https://docs.citrix.com/en-us/receiver/windows/4-9/about/fixed-issues.html

if i have time will post back the result.

We downloaded on Friday and deployed to some of the most troublesome workstations. So far it has resolved all of our Alt-Enter issues in Excel and WordPerfect (I guess there are some people that still use it.)

4.9.1 is now available

 

When you use the keyboard shortcut "Alt+Enter" in a published seamless application, the wfica32.exe process might exit unexpectedly. [#LC8317]

Good to know Vincent. Thanks for the update!

[Vincent Alberti1709156874]

All,

 

Citrix will soon release Citrix Receiver 4.9.1000. In this version, the ALT+ENTER issue for Microsoft Excel will be fixed. I tested with a modified version of "GfxRender.dll" and I could not reproduce the error anymore with this fix.

 

So my advice would be to wait upgrading to Citrix Receiver 4.9, till version 4.9.1000 is available for download, which will be very soon.

[Patrick Braam1709152867]

Noticed this at a customers' site as well, Excel turns into black screen. Waiting for the next Receiver version.

[Vincent Alberti1709156874]

Same was happening to me. I tested with Receive versions 4.8 and 4.9 on Citrix XenApp 7.13 and 7.15. I got the hotfix "LC8317-49.zip" from Citrix. This hotfix contains 1 file, "GfxRender.dll", with a date stamp of Sept 1st, 2017. I replaced the GfxRender.dll in c:/Program Files (x86)/Citrix/ICA Client with the new one from the hotfix and rebooted my laptop with Receiver 4.9.0.2539 but this issue still happens.

 

By the way, I was also told that this issue will be fixed in Citrix Receiver 4.10, which will be released by Citrix on November 17,th, 2017.

We are also using the private LC8317 and it OK now.

[Matthew Francis1709152434]

We did test a private fix for 4.9 and showed scuccess

[Tim Mallon]

We are seeing this same issue,  rolling back to 4.7 for now XenApp 7.15 ltsr and 4.8 and 4.9

We are seeing this same issue,  rolling back to 4.7 for now XenApp 7.15 ltsr and 4.8 and 4.9

[Frank Bullmahn]

We have exacly the same issue (alt+enter in Excel2010 = freez session) with Receiver 4.9 and Windows 2012 R2 / XenApp 7.13 but only on some clients. Reinstalltion the receiver allthough with the cleanup-tool will not be succesfull. Are there any workarounds?

[Stephane Pietrzykowski]

Same issue too with Receiver 4.9 and Windows 2012 R2 / XenApp 7.13. Any update ?

[Justin Agger]

Case opened with Citrix Support for the issue, traces were collected and uploaded.  Initial analysis indicates this is a new defect.  Waiting for more details.

[Elliot Tempest]

Can confirm this is an issue in 4.8 and 4.9, after rolling back to 4.7 alt and enter functionality was restored. 

[Wendell Pinegar]

I went back and installed 4.8 and I'm not able to reproduce this issue any more. Maybe this is an Citrix Receiver upgrade related problem. To NOT reproduce the issue I've uninstalled 4.9 and reinstalled 4.8 and I don't see any issues with using ALT-ENTER inside an Excel published app.

[Matthew Francis1709152434]

I can confirm that the issue still exists after 4.9 too

[Wendell Pinegar]

We were not able to reproduce this issue on Receiver 4.9. While we have other issues with 4.9 (ie, unable to launch published content) the ALT-ENTER issue in a Microsoft Excel published app wasn't reproducible after we upgraded to Receiver 4.9.

[Jake Clark]

Same issue here - following for resolution!

[Justin Agger]

Same issue was reproducible using Receiver 4.9 as well.

[Matthew Francis1709152434]

Receiver 4.9 is now available. Testing to see if issue is resolved.

[Matthew Francis1709152434]

We have seen this at one customer so far where the Receiver does the black screen or crashes. Tested with 6.5 without issue only seems to effect 7.x from testing.

[Jan Bonne Eringa]

In our XenApp 7.13 on Windows Server 2012R2 we have this issue with the Receiver 4.8 as well.

 

Could it have something to do with Window Mode? As Alt-Enter is also a shortcut for forcing Window Mode (https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts#Window_management)...
