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

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!

I can't replicate the problem, 3.2.8.1 and WinXP Pro SP2

^ thanks for testing ^

in the first post i forgot to mention that my autoit version is 3.2.8.1 and OS is WinXP Pro SP2, too.

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.
