I'm do believe thats the same script that is included in Hera but I am not exactly sure. I think that the way Hera executes it causes it to have a problem but quite honestly that's a simple and basic script. I do not see a point into adding it to Hera when all you do have to do is run it by itself. Bind a key to "sw_toggle" and it works like magic. I recommend having a speedhack to go with it because it works greatly for me at least. That's as far as I can help since its 5am here and I'm posting this from my phone. Hope it helps.
