Thanks for trying to help jmcilhinney. No, problem.
Actually my code is very simple. I have an image that is screenshoot of currently screen. Then, with rolling mouse, i zoom it + or -. Nothing more.


'zooming down
If e.Delta < 0 Then


If img_zumiranje.Height > System.Windows.Forms.Screen.PrimaryScreen.Bounds.H eight And img_zumiranje.Width > System.Windows.Forms.Screen.PrimaryScreen.Bounds.W idth Then
For i = 0 To 12
img_zumiranje.Height = img_zumiranje.Height - System.Windows.Forms.Screen.PrimaryScreen.Bounds.H eight * 0.1
img_zumiranje.Width = img_zumiranje.Width - System.Windows.Forms.Screen.PrimaryScreen.Bounds.W idth * 0.1
img_zumiranje_MouseMove(Nothing, Nothing)
Next
End If

End If

' zooming up
If e.Delta > 0 Then

If img_zumiranje.Height < System.Windows.Forms.Screen.PrimaryScreen.Bounds.H eight * 5 Or img_zumiranje.Width < System.Windows.Forms.Screen.PrimaryScreen.Bounds.W idth * 4 Then

For i = 0 To 12
img_zumiranje.Height = img_zumiranje.Height + System.Windows.Forms.Screen.PrimaryScreen.Bounds.H eight * 0.1
img_zumiranje.Width = img_zumiranje.Width + System.Windows.Forms.Screen.PrimaryScreen.Bounds.W idth * 0.1
'img_zumiranje.Refresh()
img_zumiranje_MouseMove(Nothing, Nothing)
Next
End If
End If

But, i must also mention something strange that i remark tonight. Some buttons on my form that should react on ONE mouse click, react only on double mouse click. I really do not understand.
p.s. this is my first post ever. So please forgive me if i did not made it in suitable form (i mean code)

Thanks

I discovered problem. There was also one little form in my application that was set to top most. That was problem. Thanks jmcilhinney for trying to help.
