I am trying to automate an old app and I encounter some issues.

The main Window is ClassName=ThunderRT6MDIForm
The child Windows are ClassName=ThunderRT6FormDC
Buttons are ClassName=ThunderRT6CommandButton
Some tables are ClassName=MSHFlexGridWndClass (no children detected)

I am able to read the application state but...

• Invoke() on buttons result in: the requests pattern Invoke #10000 is not supported
• Click() buttons have no effect
• Focus() buttons have no effect

Tested with UIA2 and UIA3.

Anyone knows what UI framework it is?

Do you have any idea how I can click buttons?
