Summary0001640: TJvDBGrid 1.44 crash in CanEditShow (access violation)
Descriptioncrash on the line:
    F := Fields[SelectedIndex];

to be protected I modify the function to the following version:
function TJvDBGrid.CanEditShow: Boolean;
var
  F: TField;
begin
  Result := inherited CanEditShow;
{ F := nil;
  if Result and (DataLink <> nil) and DataLink.Active and (FieldCount > 0) and
    (SelectedIndex < FieldCount) and (SelectedIndex >= 0) and
    (FieldCount <= DataSource.DataSet.FieldCount) then
  begin
    F := Fields[SelectedIndex];
    if F <> nil then
      Result := GetImageIndex(F) < 0;
  end;
  }
  if Result and Assigned(FOnShowEditor) and (DataLink <> nil) and DataLink.Active and (FieldCount > 0) and (SelectedIndex < FieldCount) and (SelectedIndex >= 0) and
    (FieldCount <= DataSource.DataSet.FieldCount) then
  begin
     F := Fields[SelectedIndex];
     FOnShowEditor(Self, F, Result);
  end;
end;
Additional InformationCrash appends when the dataset used by the dbGrid is modified or replaced.
