When menu item is clicked (e.g. File or Edit) in Notepad exception occurs using FLAUI

[dardanshabani]

An outgoing call cannot be made since the application is dispatching an input-synchronous call. (Exception from HRESULT: 0x8001010D (RPC_E_CANTCALLOUT_ININPUTSYNCCALL))

This message is shown when I try to instantiate new automation element from point at mouse click events, using mouse hooks also.

Code snippets var clickedElement = Uia3Automation.FromPoint(e.Location);

Can you provide some more code? If I just use

var automation = new UIA3Automation();
var clickedElement = automation.FromPoint(Mouse.Position);

while the mouse is over any menu or object (even in notepad++), it works correctly.

What is the value you get on clickedElement? is it MenuItem or Menu?

[Roemer]

It is MenuItem. Regardless of If I use the File menu or any item below.

But when I use an submenu-item, this item is not directly in the tree below the "File MenuItem", instead it creates a new "File Menu" item in the root which contains the subitems as MenuItem. See:
