Won't let me type the letter "r" in notes

Hi guys, I've noticed something very strange. When I go to write something in notes down the bottom area it will not let me type in the letter "r" for some reason. Everywhere else is fine but not in the notes section. Have you come up with this before?

Buggered if I know? (Australian slang)

Hi Grant,

I just now tried it.  Works for me.

Yeah, I just found out,  it's just this particular computer that's doing it. Weird stuff!
