Object snaps are wonderful things, but occasionally you don't actually want to use them. For example, intersecting lines in a hatch pattern probably aren't part of your design, and you'd rather not have them appear as an option when you're looking for intersections.
Fortunately, removing hatches as object snap targets is simple. Just go to the Options dialog, Drafting tab, and check the box marked "Ignore Hatch Objects" under "Object Snap Options". (You can also use the system variable OSOPTIONS.)
