How do I prevent sticking of tentative snap?

I recently added memory to my system and immediately my snap lock began acting up. I do not use AccuSnap. Whenever I tentatively snap on an element, the cursor sticks on that point until I use the reset button. Then, normally that would cancel the operation, but it just releases the tentative snap to allow me to snap elsewhere. I am not accustomed to that and I want to be able to cycle through tentative snaps without having to reset. 

Is there a setting that controls that?
