>Thank you, Dmitry. I hope your desktop's "desktop" didn't get messed up too much, after the rotations (since the command button is the only input control of the form, pressing space is sufficient to circle around, but I know what you mean, it gets weird trying to reach for the command with the mouse when the screen is rotated).

I copied the program to the Window 10 tablet via USB (no problems with WD). Now your program correctly responds to me turning the tablet to portrate or landscape. That is, the word "Portrate" changes to "Landscape" on the form, and back. Is this what you were trying to confirm?
