Description
The TDriveComboBox.OnChange event is called twice when the selection made by the user is not the currently selected drive.
Steps to Reproduce:
Drop a TDriveComboBox on a form and give it an OnChange event.
Set a breakpoint or do something that will allow you to detect when the event handler is being called.
Run the application and change the currently selected drive.
You should see the event handler called twice every time the drive is changed.
