How to play back a select choice from un Autocompletion list in Test complete V10.40

My problem is that as soon that I enter a text in the textbox, it appear an autocompletion list witch I can select a choice that is display Under the textbox itself. It is that event of the autocompletion list that TestComplete seems to not recognize. As long as I do not make appear that list manually Under the textbox, TestComplete is not capable to reconize the object. It seems to be invisible for TestComplete on a playback. Could you help me to reproduce that event in a keyword test or a script.
