[paragui-users] Listbox select and add

[Craig Thornton]

Andrew,

    Here is the code that works if there are no items in the listbox selected. When an item is selected and access violation occurs. This happens when the function is exited, and the return value set true/false doesn't fix it. The variable b tries to get the item that is selected and unselect it. This doesn't work.
