We have one bug at UniListView at Windows 2003 Server
We use ListView with Full Row Selection
Moving with navigation keys Up and Down.
Drawing selection mark line is spitted after resize (enlarge) the last column.

STARTING VIEW

|{ column A }|{ column B }|{ column C }|
| | | |
======================================================
| current | selection | | = selection highlight (no ghost/fragment)
| | | |
| | | |
------------------------------------------------------


EXPANDED column C VIEW

|{ column A }|{ column B }|{ column C }|
| | | |
=================================================================
| current | selection | | = selection highlight (no ghost/fragment)
| | | |
| | | |
-----------------------------------------------------------------



CURSOR UP AND DOWN


|{ column A }|{ column B }|{ column C }|
| | | |
=================================================================
| | | | = selection highlight ghost
| | | |
| current | selection | | = selection highlight fragment
| | | |
-----------------------------------------------------------------

Could you try trapping the key events and forcing a redraw?

If i add refresh to LvObj_ItemClick all fine then on each click screen blinks

Private Sub LvObj_ItemClick(Index As Integer, ByVal Item As UniToolbox2.ListItem)
LvObj.refresh
End Sub

If I add to LvObj_HeaderMouseUp it is not work .

Private Sub LvObj_HeaderMouseUp(Index As Integer, Button As Integer, Shift As Integer, X As Single, Y As Single, ColumnIndex As Integer)
LvObj.refresh
End Sub

The problem only Windows 2003 , Windos XP works fine

Well VB6 wasn't exactly built for Windows 2003!

Try double debuffering everything, that should minimize any flickering.

This should explain how:

It's a lot harder in VB6 than in .NET where it's simply a property on the controls.

I did not get how it will help?
We do not have any pictures on a form except icons in UniList.

If you take the concept of double buffering from that article you can apply it to a variety of controls.
