hi,

$GUIHeight = 480

$hGUI = GUICreate("ListViewHeader", $GUIWidth, $GUIHeight, -1, -1, BitOR($WS_MAXIMIZEBOX,$WS_MINIMIZEBOX,$WS_SIZEBOX,$WS_THICKFRAME,$WS_SYSMENU,$WS_CAPTION,$WS_OVERLAPPEDWINDOW,$WS_TILEDWINDOW,$WS_POPUP,$WS_POPUPWINDOW,$WS_GROUP,$WS_TABSTOP,$WS_BORDER,$WS_CLIPSIBLINGS))

$Tab1 = GUICtrlCreateTab(13, 13, $GUIWidth-32, $GUIHeight-58, BitOR($TCS_FLATBUTTONS,$TCS_BUTTONS,$WS_GROUP))
; TabSheet1
$TabSheet1 = GUICtrlCreateTabItem("TabSheet1")

Next
GUICtrlCreateTabitem("")
GUISetState(@SW_SHOW)

While 1
$nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

as you can see in the attached image, each time I run this script, the GUI opens but after 5-10s the headers of the listview seam to disapper. as soon as i move the mouse over them, they are visible again.

why do they disappear?

Is this a problem with my script (or autoit) or is my comuter causing it?

maybe someone could test this script and tell me if he/she can reproduce my error.

thanks in advance!

maybe some trouble with the graphics card?

I've seen this too, but have cured it since - I can't remember exactly what I did, but I do know that my code to create the ListView looks identical and I now perform these actions -

; Resize to make sure we can see the command OK
_GUICtrlListViewSetColumnWidth ( $ProcessListView, 4, $LVSCW_AUTOSIZE )
        
; Hide and re-show, to refresh
GUICtrlSetState ( $ProcessListView, $GUI_HIDE )
GUICtrlSetState ( $ProcessListView, $GUI_SHOW )

I don't send

GUICtrlSendMsg($ListView1, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES)

and I'm almost certain I did use GUICtrlSendMsg() before - this may be part of the problem?

A little vague, but hope it helps.
