UniDBGrid, columns visibility

[Rav]

Hello,

I tried to save and restore UniDBGrid columns visibility like this:

  for cb := 0 to dbg.Columns.Count - 1 do
    with dbg.Columns[cb] do
      UseFields[cb] := Visible;
............................
  for cb := 0 to dbg.Columns.Count - 1 do
    with dbg.Columns[cb] do
      Visible := UseFields[cb];
.............................

Then found weird thing that after some actions (e.g. opening another dataset) the property "Visible" of ALL columns even invisible of this dataset becomes "True".

Actual columns visibility remains unchanged.

Version uni-0.99.96.1321 (with 0.99.95 version the situation is the same)
