Is this a One Note Problem?

[hitman]

Today writing in One Note in my own handwriting, the text/handwriting began to delete itself letter by letter! Trying again after writing each sentence the words would delete themselves. I gave up using One Note but later on things were back to normal and One Note worked fine. Anyone ever have this problem before?
Cheers
