Dynamics AX 2012: Forms on opening hide behind in the back

  • Article

 

In Dynamics AX 2012, when you open the forms, you might see some of them open behind the other forms. User may get the impression that the form was never opened. This happens if the form opened slowly; a cold start, uniqueness of the data including large number of records or complexity of the form may cause the form to load up slowly. The form hide behind the other form because of Windows’s ‘ForegroundLockTimeout’.

Doing the following changes to your system could fix this issue. Since it involves changing a registry key in your system, take necessary precautions.

Create a Restore point before performing the steps below as a precaution.

    Thanks for info. Do we need to change it for all the user machines?

    @Yogesh Kasat: Yes, this will need to be done on each machine which is running the AX client.

    We have also tried this and it didn't resolve it for our customer.However we have a working theory that that the problem manifests itself on clients running windows 7/Win2k3 Terminal server or earlier, since we are unable to reproduce our customer's problem on the MS Contoso system running win2k8. Perhaps the performance team can investigate this angle ?

    We have the same problem. We are running AX-client as remote app on Windows 2012 terminal servers.Changing the register key didn’t fix it for us.Only Windows 7 users have this problem, Windows 8 user’s seems to be fine.But we found a workaround.Make sure that language bar is open and visible on the taskbar when the remote session is running.To do that:Let the user login with Remote Desktop to the terminal server Go into Control panels and Language Add at least one extra language. Go into Advanced settings Make sure that “Use the desktop language bar when it’s available” is checked Click on Options to the right In the options for the language bar make sure that ”Docked in the taskbar” is selected. Apply all settings and log out of the Remote Desktop Start the remote app again and the windows will behave normal again

    Registry changing did not resolve problem in my company. Adding extra language also not working (windows 2012 RDP, remote app on windows 10/8/7). Has anybody solved the problem?
