VFP 6.0 SP1

Here are the non-default properties of my form:
AutoCenter = .T.
BufferMode = 2 - Optimistic
DataSession = 2 - Private data session
Height = 107
ScrollBars = 3 - Both
ShowTips = .T.
ShowWindow = 2 - As Top-level form
Width = 394

After saving the form and I opening it again, the width is changed to 386 (the vertical scroll bar appear).

Has anybody encounter this problem ?

TIA
