Stop SolidWorks from "tracing" a sketch

Every time I want to edit a sketch, feature, etc. I right click on it in the Feature Manager Tree, but before it will let me do anything, SolidWorks traces that particular feature, and it can sometimes takes upwards of a minute to complete before I can make any sort of changes. Is there a way to turn that "tracing" function off, or  make it move more quickly.
