I created a fix that works for me. See code market with //HTG

procedure TacVirtualTreeViewWnd.AdvancedHeaderDraw(Sender: TPersistent; var PaintInfo: THeaderPaintInfo; const Elements: THeaderPaintElements);
…
…
if hpeDropMark in Elements then begin
{$IFDEF TNTUNICODE}
Text := GetWideStrProp(PaintInfo.Column, 'Text');
{$ELSE}
Text := GetStrProp(PaintInfo.Column, 'Text');
{$ENDIF}
if Text <> '' then begin
TextRC := PaintInfo.TextRectangle;
OffsetRect(TextRC, -PaintInfo.PaintRectangle.Left, -PaintInfo.PaintRectangle.Top);

HeaderProp := GetObjProp(SkinData.FOwnerControl, 'Header');
if HeaderProp <> nil then begin
FontProp := GetObjProp(HeaderProp, 'Font');
if FontProp <> nil then begin
Bmp.Canvas.Font.Assign(TFont(FontProp));
end;
end;

// HTG
Flag:=DT_VCENTER or DT_END_ELLIPSIS;
if WrapCaption(PaintInfo.Column) then
Flag:=Flag + DT_WORDBREAK
else
Flag:=Flag + DT_SINGLELINE;

acWriteTextEx(Bmp.Canvas, PacChar(Text), True, TextRC, Flag, Si, (State <> 0), DefaultManager);
// HTG
end;
end;

function TacVirtualTreeViewWnd.WrapCaption(Column: TCollectionItem): Boolean;
begin
Result:= Pos('coWrapCaption', GetSetProp(PaintInfo.Column, 'Options'))>0;
end;
