that is called the 'run aways'... if you have WASD on the do-not-pass (DNP) list, then anytime you hit shift+WASD.. you can hit the run-aways.

with v1.8i i introduced 'strict' to the DNP. this is basically the old way of doing the DNP.. where you would have to specify every possible key. unchecking strict and any modified version of the key will be blocked... thereby avoiding the run-away

if you want to use strict.. then just add shift+WASD, ctrl+WASD and alt+WASD to the DNP.
