[paragui-users] PG_DropDown DeleteAll

[address@hidden]

Hi~
        I am using ParaGUI-1.1.8.
        After I used DeleteAll() to clean the dropdown list, then
AddItem() to add some new items to it.
        The dropdown list is not draw correctly.
        Some codes like this:

        PG_DropDown* drop = new PG_DropDown(this, PG_Rect(260, 60,
200,25));
        drop->SetIndent(5);
        drop->SetAlignment(PG_Label::CENTER);
        drop->AddItem("Under construction");
        drop->AddItem("Item 1");
        drop->AddItem("Item 2");
        drop->AddItem("Item 3");
        drop->DeleteAll();
        drop->AddItem("Item 4");
        drop->AddItem("Item 5");
        drop->AddItem("Item 6");

        Then I cant see or click the slot of "Item 4".
        Any comments?   Thanks.
