FIX: MouseDown Event Fires Unexpectedly on Modal Form (257543)

MORE INFORMATION

Steps to Reproduce Behavior

1. Start a new Standard EXE project in Visual Basic. Form1 is created by default.
2. From the Project menu, add an additional Form and a UserControl to the project.
3. On both Forms, set StartUpPosition = 2 - CenterScreen.
4. Add a Textbox, a CommandButton, a UserControl to Form1.
5. Add the following code to the code window of Form1:

   Option Explicit
   
   Private Sub Command1_Click()
       Debug.Print "click"
   End Sub
   
   Private Sub Form_Load()
       Text1.Text = ""
       Text1.TabIndex = 0
   End Sub
   
   Private Sub Text1_Validate(Cancel As Boolean)
       Debug.Print "Form1 Text_Validate"
       If Text1.Text = "" Then
           Form2.Show vbModal
       End If
   End Sub
   					

6. Add the following code to the code window of Form2:

   Option Explicit
   
   Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
       Debug.Print "Form2 Form_MouseDown"
   End Sub
   					

7. From the View menu, click on Immediate Window to open the immediate window.
8. Save and run the project.
9. When you click on Command1 of Form1, you will see in the immediate window, that the MouseDown event of Form2 gets fired after the Validate event of Text1. This is not the expected behavior.
