I just reread the thread and what you wrote to give that impression is
quite clear to me. I suggest you do the same to review what you said and
to re-evaluate what people have suggested.

I'll offer one further suggestion:

In order to determine the column widths, first see if the treeview
exists and if it does, ask it. If it doesn't exist, read the widths from
a file.

Create and maintain the file by hooking the destroy and delete events as
Gorshkov suggested.
