>On my form I click a button that populates a list box and makes it visible. When an item in the list is selected it populates a text box and then becomes invisible. All this is okay so far. However, when I click the button again the list box appears okay but when I try and click the scroll bar to find my item the value that was selected the previous time is inserted into the text box. Its like the click event the second time around is triggered when the list box is clicked on event though I didn't select an item.

Steven,

What's VFP version? Did you try to trace events in the Debugger to see what triggers that click event?
