Most probably that is a trivial question:  obviously I am not a
specialist....

I am adding items to a Listbox using the AddItem.What I am doing is
manipulate several files and I would like to see in my ListBox how the
processing is proceeding (things such as:

 a.. Time-1 File1 copy started
 b.. Time_2 File1 copy completed
 c.. Time_3 File2 renamed to xxxx
 d.. Etc)

What happens is that the program starts, the ListBox is shown - empty - and
only when the program terminates all the added items are shown in the box
and that obviously is not what I want to do.

What am I doing wrong? Thanks
