Duplicate entries in drop down box

I have several predefined values in the properties dialog of a drop
down CComboBox which get duplicated at run time.

I tracked the number of elements in the drop down box via
CComboBox.GetCount() and discovered that when my program creates a
thread, which receives a pointer to the dialog, the number of elements
in the drop down box doubles when I cast the dialog:

void Thread(void *lpParam)
{

CInstrumentStatusDlg * pIS = (CInstrumentStatusDlg *)lpParam;

then pIS->dropBox.GetCount() returns 2x the number of required
elements


I'm guessing that when I call (CInstrumentStatusDlg*), it repopulates
the values in the drop down box... which is strange, I'd suppose MFC
would not allow that to happen. How do I prevent this from happening?
Singleton implementation? Manual addition of values to the drop down
box? Something else?
