Problem: Using wxPerl wxComboBox control produces an "error sound" when TAB key or RETURN key is pressed inside the focused control.

Question: Does anyone know the mechanism for disabling this? So far, search has turned up nada.

Background: Consider the standard "modal dialogs" in msft windows (file-open dialog is an example). If you open the dialog box, and then click your mouse anywhere *outside* the dialog box, the system produces an "error sound" such as a beep or something similar, as if to say "Hey wait a minute! First deal with the dialog box!" Well, this is exactly the sound that occurs if you press return or tab while focused on a wxComboBox control. It would be nice to get rid of that, hence the question.
