Hi all. I hope you can help.

1. I am using my laptop on a second screen with screen settings at 'second screen only'
2. When I try to play a Powerpoint show (I do a lot of work in Powerpoint) and I go to close the show, the computer defaults back to 'extend screens' and I have to manually reset the screens.

Seems to be some issue with my defaults but I can't work out how to fix it. Would appreciate any help.
