Combo Box Odd Display Behavior

I'm getting an odd display behavior in my combo boxes since switching to EU4. If the drop down list has more than 30 items then the empty space to right of the list's items has a black background instead white. As I mouse over the list the black disapears as the pointer moves over each item. Also any movement of the right scroll bar clears all the black. I'm using w32lib v0.70.18 and Vista Home Premium SP2.

Below is a sample program the demonstrates the effect on my system.

include Win32lib.ew 
constant MainWindow = createEx(Window, "Combo Box Bug Test", 0, 100, 100, 440, 100, 0, 0) 
	constant ComboOne = createEx(Combo, "", MainWindow, 8, 10, 200, 0, 0, 0) 
		for x = 1 to 30 do 
			addItem(ComboOne, "Combo One")			 
		end for 
		setIndex(ComboOne, 1) 
	constant ComboTwo = createEx(Combo, "", MainWindow, 220, 10, 200, 0, 0, 0) 
		for x = 1 to 31 do 
			addItem(ComboTwo, "Combo Two")			 
		end for 
		setIndex(ComboTwo, 1) 
WinMain(MainWindow,Normal)
