Hi Allan thanks for responding.
I have made a 2 minute video that demonstrates what I am trying to do within PowerPoint
http://qlnk.io/ql/57b1e3d5e4b05a25f975f8bd
And here are a few screen caps from that video:
1 - pasted an image into a blank slide
2 - DESIGN IDEAS is switched on and PPT offers a set of layouts. I select the second one
3 - in the SELECTION PANE I can see that PPT has added two text boxes and two 'FREEFORM' objects which I can switch on or off and also can change the colour, transparency and outline style.
The only way to select the new objects on the slide is from the SELECTION PANE. It is not possible to click on these objects in the slide area.
However, the bounding box for the FREEFORM items is visible when the item is CTRL CLICKED in the SELECTION PANE and at that point the colours can be edited.
There are no Re-Sizing handles on the bounding box for the new items, nor is there any way to re-postion them - their SIZE and POSITION dialogue boxes are greyed out.
It follows therefore that these new items are partially locked (size and position).
So my question is - how do you unlock items added by PowerPoint Designer and then, having edited them, re-lock them so they cannot be edited (accidentally) by someone else?
I do hope you can throw some light on this as it would be very useful to know the answer.
