Hi again Barb
I have version 8 of Adobe Reader.
I open the pdf I want to copy a diagram from.
On the Tools menu, I go to Select and Zoom then choose the Snapshot
tool. My cursor turns to a crosshair sort of thing.
I then draw a box around the photo/chart/diagram I want to copy.
The screen flashes, and there's a popup message telling me that the
selected area has been copied.
I then go to PowerPoint and paste. Voila!
HTH
