Not too sure, I examined every inserted image in the presentation, now
I've had time to investigate, and it appears two of the images have been
dragged from a foreign picture editor so it came in as an "object" and
will look for the app to edit it, also some of the images, if you right
click on them, instead of the usual "change picture" you also get "edit
picture" which of course says "this is an imported picture, not a group,
do you want to convert etc."
So it seems that there are two instances, an imported image or an object
created by dragging from a picture editor application.
With the chance of answering my own post, on further investigation of
how to circumnavigate this "feature", if you put all the presentations
in a specific folder and add this folder to your "Trust Centre > Trusted
Locations" it seems to cure the pop up security alert.
Not really an answer, more a work-around, which makes a mockery of the
original purpose of the alert,
Really need a better solution as not all technicians fully understand
the reason behind your logic and this has only cropped up in 2007, the
macro security in previous version normally cured the warning without
the need to have a specific directory allocated for the purpose.
