range selection tool and editing problems

I have a hard time seeing the edge of parts when i use the range selection tool for cross fades. When I choose the range selection tool, the edges of the parts turn from red to grey and it makes it difficult for me to see the line(s) separating the parts underneath the range I have selected…

Is there a way to accentuate the the edges of the parts so that i can see more clearly when using the range tool for cross fades?
