No example, because I deduced that anyone unfamiliar with the problem would be unfamiliar with a fix. If you have wxPerl on your system, however, you can run the following script to see what I am talking about:

## Name:        controls.pl
## Author:      Mattia Barbon
[download]

If you don't have the script just Google for the Name and Author and you will find a copy of it.

• run the script
• choose the "Wx::ComboBox" page
• set focus on the ComboBox control on the page
• make sure your computer speakers are activated
• press the TAB key or the RETURN key
• listen
