Yes, exactly. And I am not sure why, but now it looks like that! Maybe the latest update? Or a restart?
I have tried many things - but now I have default Windows set to dark, default app to 'light', transparency to 'on' and it is holding the theme background when in tablet mode. The themes are ones I have downloaded
from Microsoft and I will see how it goes when I change, which I usually do with the seasons.
The only other thing I have noticed is that my old Surface used to change to/from tablet mode whenever I detached/attached the keyboard; With this one it does not happen automatically. Not a big deal, just different.
Thanks for your help!! kathie.
