Help Call reject popup prevents swiping to answer call

[aamyot]

Often when a call comes in, the popup from the bottom of the screen with Reject Messages interferes with swiping to answer the call. It sort of vibrates up and down. As soon as I try to swipe it gets in the way and I can't answer the call.

Is this because of some particular way that I am touching the screen?

The only thing I can think of is if you either have a rather heavy duty screen protector attached or if you have more digits touching the screen when sliding to answer than the digit used to perform this function.
