I have run in to a problem with Windows XP and Access 2000. My application with a form that has 2 list boxs on it, the second list box has a criteria set that gets its value from the first list box. So when an item in the first is clicked it does a requery on the second. When I close the form it asks me for the second list box parameter. This only occurs if I have more than 18 items in the second list box and only with Windows XP.
