Post a screenshot of your event handler code please. It's almost impossible for us to tell what is happening from just an error message.
Dear Marsha_R!
I didn't attach eventhandler code, because testcomplete never hit the eventhandler script.
The attached error message shows the point, when testcomplete should call the eventhandler, but for me it seems like, the engine doesn't recognise it's an unexpected window event, only that the tested window is disabled.
Additionally i followed the setting steps of event handling described like in the related section on this page: https://support.smartbear.com/articles/testcomplete/handling-unexpected-windows/
Thanks,
Benjamin
Then let's see the code from the "keyboard input" line on down to where the error happens.
