In a few rare instances, treeview control fails in third party applications when Automatic Keyboard Display policy is enabled. 

The following failures have been observed:  
•             Treeview fails to load.
•             Treeview loads; however, users are not able to click on any items.
•             Treeview loads and results in application crash.

These failures are due to Microsoft UI automation framework interaction with old Visual Basic treeview control (TreeViewWndClass from COMCTL32.OCX)
  
Microsoft recommends to migrate the project code of the application to utilize the newer version treeview controls.

Disabling Automatic Keyboard Display policy for Virtual Apps and Desktops is recommended as a workaround.
