I'm coding an app in MSVS 2008, which has a ComboBox control which I initialize thru the code as below:

static char*                    OptionString[4] = {"Opt1",
                                                   "Opt2",
                                                   "Opt3",
                                                   "Opt4"};

BOOL CMyAppDlg::OnInitDialog()
{
    CDialog::OnInitDialog();

 // Set the icon for this dialog.  The framework does this automatically
 //  when the application's main window is not a dialog
 SetIcon(m_hIcon, TRUE);   // Set big icon
 SetIcon(m_hIcon, FALSE);  // Set small icon

    // TODO: Add extra initialization here

    m_Option.AddString(OptionString[0]);
    m_Option.AddString(OptionString[1]);
    m_Option.AddString(OptionString[2]);
    m_Option.AddString(OptionString[3]);
    m_Option.SetCurSel(0);

    return TRUE;  // return TRUE  unless you set the focus to a control
}

Now, when I build the app and click the down-arrow, the drop-down box shows the first option ONLY(since I've selected that thru my code). But, if i press down-arrow key on keyboard, it cycles thru the options in the order I've inserted, but never does it show more than 1 option in the box. So, In case an user wants to select option3, he has to cycle through options 1 and 2 !! Though once I select any option using the keyboard, the appropriate event handlers are fired, I'm miffed by this behaviour , as is understandable.

I'm listing the properties of the combo-box control as well - only the properties that are true(rest are set to false):

1. Type - Dropdown
2. Vertical Scrollbar
3. Visible Tabstop

This has bugged me for weeks now. Can anyone pls enlighten me ?
