I'm still in CE land and I've definitely seen this and it is very
easy to reproduce. For me however the difference is both up and
to the right, the digital ink line is close to 45 degrees but just
a little close to vertical I think. I'm glad you pointed this out
because I was beginning to think I was loosing my writing ability.
I just have to make sure to tap faster now I guess.
