Entire functions sharing simple $a$-points with their first derivative   II
  We discuss some results around the following question: Let $f$ be a nonconstant complex entire function and $a$, $b$ two distinct complex numbers. If $f$ and its derivative $f'$ share their simple $a$-points and also share the value $b$, does this imply $f\equiv f'$?
