Pasting Graphics from the Clipboard to PowerPoint for OfficeX

[Sez]

Hello team,

We have students trying to copy graphic items from Safari and paste
them into Powerpoint presentation. Things started out fine in the
morning, however as the day wore on, the graphics would appear in the
PowerPoint document up side down. Literally. Anyone know what would
cause this? Graphics imported fine if they saved them to the hard
drive first.
