Hi,

We have a MFC MDI Application that contains custom WebBrowser ActiveX Control and other objects (such as buttons).

The Web browser control has a pre-set URL which prompts for login. This login dialog is from the Internet explorer 11 and is the type of "Credential Dialog Xaml Host" windows security login dialog. After entering the credentials if we click "OK" or "Cancel", other objects other than Web Browser Control in the MDI application are not operable using mouse click.

We also notice that there are no MOUSEMOVE messages detected in SPY++ tool when we hover the mouse around in the application.

The issue is observed only when there is a windows security dialog of type “Credential Dialog Xaml Host" coming up from the IE.


In Windows 10 OS machine with the latest update of IE 11.0.105, KB4480965, "Credential Dialog Xaml Host" windows security login dialog is coming up.

But in Windows server 2012R2 OS machine, with the same update of IE 11.0.105, KB4480965 the old windows security login dialog box of type "DirectUIHWND" is coming up instead of "Credential Dialog Xaml Host" class type, where the issue is not reproducible.

Is there any way to enable old dialog box of type "DirectUIHWND" rather than using "Credential Dialog Xaml Host" type dialog in windows 10 OS machine as well (with latest update of IE 11.0.105, KB4480965)? So that it can resolve above issue.
