C# WinForms Win 10 issue: Network credentials (connect via intranet) dialog fails on touch

We encountered these Win 10 issues on a WinForms app using WebBrowser component to connect on a touch tablet with Network Credentials to intranet:

OS: Window 10 IoT Enterprise 2016 LTSB (version 1607)
Device: AEGEX 10 tablet

Issue1 Description:

  • C# Winforms app using WebBrowser component compiled with VisualStudio 2022 running on touch tablet.

  • Try to connect to intranet via https://login.microsoftonline.com, after entering email address will be automatically forwarded to company login (Enter Network Credentials Dialog).

  • Entering user name and password with touch via OSK (on screen keyboard) works

  • Issue 1: Touching OK or Cancel button or “Remember my Credentials” check box does not work. Buttons will be focused but no reaction.

  • Issue 2: After trying to touch ok or cancel touching the background caller app (WinForm with WebBroser component) the complete app hangs.

  • Issue 3: Same thing happens if using AcquireTokenInteractive (with embedded web browser).
