OnClickSeries works "randomly" in a Tag Cloud serie

After upgrading to 2013.09.131119, the OnClickSeries event in a Tag Cloud serie works "randomly" - I mean it gets fired seldom as long as I try clicking around the chart. While with version 8 I could get reliable result, with version 2013 it looks the code to identify the click site can no longer identify reliably when a tag in the tag cloud is clicked.
Is there any change between version that requires a different approach?

Hello,
I'm trying to reproduce the problem with the following code but it seems to work fine for me here in Delphi 7 with both TeeChart v2013.09 and the actual v2014.11.
Code: Select all
uses Chart, TeeTagCloud;
var Chart1: TChart;
procedure TForm1.FormCreate(Sender: TObject);
begin
Chart1:=TChart.Create(Self);
Chart1.Parent:=Self;
Chart1.Align:=alClient;
Chart1.AddSeries(TTagCloudSeries).FillSampleValues;
Chart1.OnMouseMove:=Chart1MouseMove;
end;
procedure TForm1.Chart1MouseMove(Sender: TObject; Shift: TShiftState; X,
Y: Integer);
begin
Caption:='X: ' + IntToStr(X) + ', Y: ' + IntToStr(Y) + ', ValueIndex: ' + IntToStr(Chart1[0].Clicked(X, Y));
end;
Could you please check if it works fine for you?
If this works fine but not your project, could you please try to arrange a simple example project we can run as-is to reproduce the problem here?
If the code above reproduces the problem for you, please tell us what IDE and OS are you using.
