I have a Windows application written in C#. Its main window opens a second window.
This second window is set to be not shown in the taskbar (win10.png)
When launching this application with Citrix Receiver on HP Thin Pro the window
icon is shown in the taskbar (thinpro.png)
It seems that either the taskbar or the Receiver is not honoring the taskbar behavior.
For version information see: thinpro-verinfo.png, thinpro-soft-verinfo.png and thinpro-svpack-verinfo.png
