Disabling a Hack after application

KHUT Version: 0.1.0.57
Operating System: Windows 7 x64
Browser: Chrome
Game: SAS Zombie Assault 4

Just a noob question, sorry guys..

How do you "disable" a hack once you've applied it using KHUT? I turned on 100% drop rate for items and since that's suspicious for MP I wanted to turn it off.. 

Do I have to refresh the page or is there a way to turn off a hack by resetting arrays or something like that w/o needing to do so?

Thanks, much appreciated

The simplest way is refreshing the page

Holy mother of fuck, really?

Locking up.
