Hi,
who can help me on this ?
since months I'm facing a problem* with a web application (a CRM) when published as remoteApp
on IE11 on top of 2012 R2.
The problem* :
- when user launches a modal window from within a main IE window/page, the Modal popup
gets hidden / focus is lost although I can see it on my client PC taskbar, nothing happens when I try
to get focus back to it.
-------------------------------------------------------
The CRM :
- runs perfectly on IE11 / win7 PC
- runs perfectly on IE8 / 2008r2 Server (the IIS server itself)
=> though no remote desktop session host role installed there so not sure the latter is a relevant test scenario
- has following hardcoded <metahttp-equiv="X-UA-Compatible"content="IE=EmulateIE8"/>
=> causes Document Mode to be 5 (Quirks Mode) on my windows 7 / IE11
=> same thing on remoteApp session + added the site to Intranet Zone andEnterprise Mode
XML file so IE 11 is running in Enterprise Mode Emulating IE8
I admit this has made less probable the issue to happen
Note that I did the test in a full RDP session and the issue is as random as in remoteApp.
Tried following without succeeding to get focus on the child window :
- ALT+TAB
- ALT+TAB+ESC
- CTRL+Alt+END play with the remoteApp's TaskManager minimize/maximize window ...
- Procexp.exe as remoteApp in same TS session then try BringTo Front / maximise / minimise etc
- NirSoft's winexp.exe with the focus options it provides... ... no success...
(that was on a test VM so please I don't break things ..)
- registry keys ForegroundFlashCount and ForegroundLockTimeOut
- disabling language bar (remoteApp's session) that shows on client's taskBar seem to reduce probability of the issue to appear.. but is not a fix
- looked at the app's javascript responsible of popping the app ... but actually it runs ok on PCs ?! so for what good…
RANDOM behavior sometimes OK sometimes KO
Although when IE11 developper tools is launched, the issue happen practically each time I test
wich keep me hoping this is not RDS/remoteApp related
I can see following existing KBs though for (2008 r2) but with similar issues …
The pop-up windows of a RemoteApp program may be hidden in Windows Server 2008 R2
and in Windows 7
https://support.microsoft.com/en-us/kb/2384602
The pop-up windows are hidden and the TS RemoteApp application stops responding
in Windows Vista, in Windows 7, in Windows Server 2008, and in Windows Server 2008 R2
https://support.microsoft.com/en-us/kb/983533
I tried to install this KB but it keep saying it is not applicable to this computer
RemoteApp program pop-up window is hidden in Windows
Any Help would be much apreciated.
Thanks.
