I have a chart, some line series with enabled marks and DragMarks tool. In the begining cursor is an arrow. After moving cursor above any mark it becomes a hand and still the same (hand-type) in every point of chart (no matter above mark or not). I suppose cursore to become hand type only above mark. So what is the problem?

Hi bairog,

This works fine for me here using latest TeeChart for .NET v3 maintenance release available at the client area. Which TeeChart version are you using?

Thanks in advance.

using System.Windows.Forms;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            lineAct.FillSampleValues();
        }
    }
}

The code above makes cursor NEVER become arrow type after once becoming hand (but dragMarks tool still working).
I've tested many possibilities and found out that making annotation unavailable or deleting it solves the problem.

P.S. I use teeChart 2.0.3203.23272
P.S. By the way in old versions (2.0.2652.22325 for example) this piece of code makes cursor NEVER become hand type

So what can you say about it?

Hi bairog,

Thanks for the information. This already works fine using latest TeeChart for .NET v3 release. I'll add this to the bug list for v2. However, v3 was published on mid-2007 so it's unlikely that this gets fixed in v2.
