pywinauto: Error message COMError: (-2147220991...) from menu_select

Hi there,

Thanks for providing this tool. I ran into one issue today. I am using the latest version of pywinauto on Windows 10 with one app coded on Winform.

After the following script is executed, I got the error message: COMError: (-2147220991, 'An event was unable to invoke any of the subscribers', (None, None, None, 0, None))

Application(backend="uia").start(apptorun)
app = Application(backend="uia").connect(path = apptorun)
windowsMain = app['Main Window']
windowsMain.menu_select("Help->About")

So my question is :

Any idea why we have this error? It seems program is waiting for this window closed.
Do we have way to set timeout for menu_select?

Thanks,

Alright. I have one workaround now. Thanks for your help.

windowsMain = app['Main Window']

help = windowsMain['Help'].select()

submenu = app['Dialog'] # Dropdown submenu is a top-level window

submenu['About'].click_input() # or .click_input()`
