timer and mousemove problems

[vbforever23]

Hi folks.

I am creating a screensaver app, using a timer to display a different picture every 10 seconds.

1. Why does my code result in an initial blank picturebox displayed for 10 seconds, and then the other pics are displayed after? I don't understand why the blank picturebox is displayed.

2. I want the form to close when the mouse is moved(the screensaver to stop running), so I set the mousemove event to close the form, but when I move the mouse, the form doesn't close. Why?

Thanks in advance.

Public Class Form1

    Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        Timer1.Start()
    End Sub

    Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
        Static ctr As Integer = 0
        Dim pics() As Image = {My.Resources._1, My.Resources._2, My.Resources._3, My.Resources._4, My.Resources._5, My.Resources._6}

        PictureBox1.Image = pics(ctr)
        ctr = ctr + 1
        If ctr > 5 Then
            ctr = 0
        End If
    End Sub

    Private Sub PictureBox1_Click(sender As Object, e As System.EventArgs) Handles PictureBox1.Click
        Me.Close()
    End Sub

    Private Sub Form1_MouseMove(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
        Me.Close()
    End Sub
End Class
