A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
I have this problem I think. To confirm I'm on topic.... On my external display, in 'Second Screen Only' mode, Powerpoint is huge. What used to be a window that took up half the screen now takes the whole screen. In 'Duplicate mode it's fine and just takes half the screen.
No problem with other Office apps.
It started just today following a Windows update (V1511 Build 10586.679), which may just be coincidence. I've never had the problem before.
So far I've updated to the latest version of Office 365 (PPT 16.0.7329.1923) and I've made the change (to 'false') in the manifest file, all to no avail.
Is there anything else I can try?
Thanks
