I have a Forms C# application where I would like to use a toolTip on one of the text boxes. I Initialize the tool-tip in the constructor of the Form class, and it works the first time. So when I hover over the text box with my mouse it works, but once the toolTip times out and it goes away, it does not re-appear when I move my mouse away and back onto the control. I would expect it to come back and I'm wondering what I'm doing wrong.

Here is how I initialize the tooltip:

        myTip = new ToolTip();
        myTip.ToolTipIcon = ToolTipIcon.Info;
        myTip.IsBalloon = true;
        myTip.ShowAlways = true;

        myTip.SetToolTip(txtMyTextBox,"My Tooltip Text");
