c# textbox problem

[cheesepie]

Hi guys,

Random problem here:

I have got a form inside a MDI Parent using this code to make it 'floatable':

        private void btn_CustMaintenance_Click(object sender, EventArgs e)
        {
            frm_CustomerMaintenance oCustomerMaintenance = new frm_CustomerMaintenance();
            oCustomerMaintenance.TopLevel = false;
            this.Controls.Add(oCustomerMaintenance);
            oCustomerMaintenance.StartPosition = FormStartPosition.CenterScreen;
            oCustomerMaintenance.Show();
            btn_CustMaintenance.Enabled = false;
        }

When I add a textbox to the CustomerMaintenance form with some text in it, it acts very strangely. If you click on the text in the textbox, usually the text cursor thing would appear where you have clicked on the text, but it doesnt, it just goes to the left hand side of the text.

If I put a textbox on the MDI page though, then that works correctly.

Has anyone else had this problem? If so, how did you sort it? If no-one has had this problem, can you try and simulate it and come up with a solution! Have been searching for over a week now and really cant figure it out!

Cheers,
William
