I've a TFrame (named Frame) with a TListView (named Frame->ListView) on it.
I've dropped Frame onto a TForm (named Form1). I added with the
ColumnProperty-Designer some TListColumns in the Form1->Frame->ListView.
My problem is that the TListColumns sometimes disappear.
I've solved the problem by adding the columns with some code but I'd like to
do this on the other way...

any solution / explanation?
