Images display issue

Hi,
When I fill the grid's cell with icon/image (I used the image Favorites) and test it in High contrast mode (To set high Contrast mode, start from control panel, click the "Accessibility options" applet. In the popup dialog box, select "Display" tab and check the "Use High Contrast" box; and click "Apply" button. B.T.W., I use Windows XP.) All the images can not be displayed. I am not sure it is Windows XP bug or AW bug? Any ideas?

Thanks,
Allan
