combo box not showing items

Question

I'm currently running vb .net 2003 on XP sp 2. I have a simple list of items defined for the combo box but when i run my app, although the box drops down, it is empty. If i use my mouse to click one of the "blank rows" in the box, the appropriate value displays in the text box above! How do i get the items to display in the drop down box. I didn't have this issue in vb 6.0. HELP!!
