3167	COM Error Handler - not always fires event	mLipok	Jon	"Discussion:
https://www.autoitscript.com/forum/topic/178424-com-error-handler-not-working-for-some-strange-reason/

Here is reproducer:
{{{#!autoit
; Initialize COM error handler
$oErrorHandler = ObjEvent(""AutoIt.Error"", _ErrFunc)
Func _ErrFunc($oError)
    ConsoleWrite(""!ERROR caught"" & @CRLF)
EndFunc

; Create shell object
$oObj = ObjCreate(""shell.application"")

;The following line should trigger COM error handler (at the last dot).
$oObj.Windows().Item(666).bzzzzzzz
}}}


Here are some of my test results:
