Sequence window too large for lap top

Not infrequently the sequence window bottom drops off the bottom of my laptop as it has too as it is too large. IN other words, it has autofilled with more potential sequences that can fit on my screen. Thus, I can not hit the resume button on a sequence. How do I shrink this with out cancelling the entire setup. I have using Google for an answer and have failed.
