PopupTrigger/PopupList/List problem.

[Peter Hamilton-Scott]

I have this in my .rcp file.
    LABEL "Date:" AUTOID AT (10 20)
    POPUPTRIGGER "DMY" ID PrefsDatePopup AT (PREVRIGHT+2 PREVTOP AUTO 
AUTO) LEFTANCHOR
    POPUPLIST ID PrefsDatePopup PrefsDateList
    LIST "DMY" "YMD" "MDY" "YDM" "DYM" "MYD" ID PrefsDateList AT 
(PREVLEFT PREVTOP AUTO 68) VISIBLEITEMS 6 NONUSABLE

At runtime, I can select one of the 6 date formats. No problem. My 
handler contains this snippet of code that looks for the event, gets the 
item selected and importantly, which one of the many popup triggers I 
have on my form. As you see, I'm only interested in the date list here:

                case popSelectEvent:
                SelectedListItem = EventP->data.popSelect.selection;
                    switch(EventP->data.popSelect.listID)
                    {
                            case PrefsDateList:
                                _Prefs.SelectedDateType = SelectedListItem;
Dbg("PrefsHandleEvent->SelectedDateType","%hd",_Prefs.SelectedDateType);
                            break;
This works fine. I respond to the event and save the selected item back 
into the preferences structure. When I relaunch my app, I get the saved 
list item and use that in this snippet of code:

Dbg("Form1DoMenu->SelectedDateType","%hd",_Prefs.SelectedDateType);
            DateList = (ListType *)FrmGetObjectPtr(Form, 
FrmGetObjectIndex(Form, PrefsDateList));
            if(DateList)
            {
                LstSetSelection(DateList, _Prefs.SelectedDateType);
            }

This works 99% fine. When I tap on the popup the correct item is 
selected and highlighted but the display shows the first item in the 
list. That is, given my selections:

"DMY" "YMD" "MDY" "YDM" "DYM" "MYD"
my saved selection might be "YDM" (selected item 3) but the form 
displays the first (item 0) "DMY". Naturally I get the selected item 
from my saved preferences and if it is set to "YDM" I'd like the form to 
display "YDM". How do I do this?

I tried the LstSetTopItem, LstDrawList and LstScrollList functions but 
those don't make any change to the screen. When I select an item from 
the list manually what I select gets displayed correctly but I want to 
achieve this from program control when the form is displayed.

Any ideas?
TIA
