OLE Objects/charts saved in older versions appearing flipped/inverted in PowerPoint 2002 or later.
Embedded/Linked OLE shapes may appear flipped, if created in
earlier versions of PowerPoint ( Prior to 2000-SR-1), when opened in
PowerPoint XP or later.
Using PowerPoint version
prior to 2000-SR-1, if an OLE Shape is selected with another native
PowerPoint autoshape and then flipped using the Rotate or Flip options, the
autoshape gets flipped and the OLE shape remains in it's original state.
However the bit of the OLE shape is set to flip. This bit is ignored in Pre
XP versions. When this presentation is saved and then reopened in
PowerPoint XP, the OLE shape will be flipped. Unlike pictures, this OLE
shape cannot be flipped back into the rightful state in XP.
