IContact::Display() cause accees violation on PPC 2003

Hi,

I am using following code snippet to display Contact information. It works
fine on Pocket PC 2002. However, on PPC2003, after the Contact dialog
showing up, if I press the 'Show Recording Toolbar' button on Notes page and
then press OK button to close the dialog, IContact::Display() will cause
access violation exception. Is this possible a bug of PPC 2003?? How can I
avoid this problem??
