How to change screen lock but keep pin

I apologize if this has been answered before, but I haven't found the answer by searching. I have a corporate-required PIN, which is fine, but I really want to turn the screen slider lock off. I've installed No Lock, but it doesn't seem to do anything. I've seen a couple of posts about this issue but no answers - is the consensus at this point that you can't disable your screen lock if you have a pin? Thanks - this is driving me nuts!

I've looked but haven't been able to find anything yet that works. I'd like to turn that off myself as I've got the pin code lock as well.

Thanks - it seems like such a simple thing that I figured someone had figured a way around it by now. Hopefully someone who knows how to fix this will chime in.
