I cant se the borders grid?

I have made a template in Off.97 - Word, and when I make a
table - with the VBA-code, its look very well, but when we
run it in XP, it do not show me the "border-line", I can
only see the "Gridlines"

We have Off.XP with SP2 now, earlyer last year we have
made a test in XP, - and it works very well

When I insert "DefaultTableBehavior:=wdWord9TableBehavior",
after "ActiveDocument.tables.Add Range..." it works, but
we have about 5000 documents, who not have this code.

Do anyone have seen this problem before?

Sub New2Tab()

With Selection
ActiveDocument.Tables.Add Range:=Selection.Range,
NumRows:=2, NumColumns:=2
.Tables(1).Columns(1).SetWidth ColumnWidth:=198,
RulerStyle:=wdAdjustNone
.Tables(1).Columns(2).SetWidth ColumnWidth:=198,
RulerStyle:=wdAdjustNone
.MoveRight Unit:=wdCharacter, Count:=2,
Extend:=wdExtend
.Tables(1).Rows.SetLeftIndent LeftIndent:=4,
RulerStyle:=wdAdjustNone
.ParagraphFormat.Alignment = wdAlignParagraphCenter
.Rows.Shading.ForegroundPatternColorIndex = wdBlue
.Font.ColorIndex = wdWhite
.MoveDown Unit:=wdLine, Count:=1, Extend:=wdExtend
.Font.Name = "TimesNewRoman"
.Font.Size = 12
End With
End Sub
