    <p>I am making a simple program that changes the image of a button when the user interact with it. When the computer mouse gets inside the button the image highlights, when the mouse clicks it gets darker and when the mouse leaves the button, the image gets norma. To accomplish this behavior I am changing the button image between 3 images, BUT when I click the button and it displays a modal control, e.g. a MessageBox, when it goes back from the MessageBox, the image in the button is still the "mouse inside" image, but the mouse is out of the button already...so I think the button1_MouseLeave event is not rising, but I dont understand why and how to repair it...can you guys help me out on this one? The code I am using is simple:</p> <pre><code>using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace teste1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_MouseLeave(object sender, EventArgs e) { button1.Image = ((System.Drawing.Image)(Properties.Resources.Botao_Del_Normal)); } private void button1_MouseEnter(object sender, EventArgs e) { button1.Image = ((System.Drawing.Image)(Properties.Resources.Botao_Del_Claro)); } private void button1_Click(object sender, EventArgs e) { MessageBox.Show("Test"); } private void button1_MouseDown(object sender, MouseEventArgs e) { button1.Image = ((System.Drawing.Image)(Properties.Resources.Botao_Del_Clique)); } private void button1_MouseUp(object sender, MouseEventArgs e) { button1.Image = ((System.Drawing.Image)(Properties.Resources.Botao_Del_Claro)); } } } </code></pre>

    1. COI think I figured part of the problem...`MouseLeave` is being fired BEFORE `MouseUp` (when the `MessageBox` is called, it fires `MouseLeave`, but when you click the OK button of the `MessageBox` `MouseUp` is called because of the click event)...so even if `MouseLeave` sets the correct image, `MouseUp` will set it back to the "mouse inside the button" image, even if the mouse is out of the button....any ideas how to solve this? `MouseHover` is not a good one, since it takes some time to get fired.
