powerpoint 2007 VBA form's window not retaining size

[Norm]

WEIRD BEHAVIOR

When I create a VBA form in PP 2007 and run the form it automatically
resizes (it width doubles). THis occur even when the are only one or
two lines of codes such as


Private Sub UserForm_Initialize()
Me.Left = 100
Me.Top = 10
end sub

However this automatic increase in width does not occure wirh this
code

Private Sub UserForm_Initialize()
exit sub
Me.Left = 100
Me.Top = 10
end sub


There is no subs for resizing or activating the form so it can not
come from there
