I am aware of that bug and I know the cause, but I just haven't been able to get motivated to fix it. The problem is that the editor is trying to modify the registry key that HotKeys uses to store the location of the keys file, but it is looking in the wrong location in the registry. It seems trivial on the surface, but once you dig a little deeper, you start to see that it will actually take significant time and effort to fix. I just don't know when or if I will get to it, since it isn't a complete show stopper.
I mis-spoke, the problem is actually that the program is looking in the registry to figure out which folder it is installed in, but it is looking in the wrong section of the registry. I'm looking into a way of fixing it that I hadn't previously considered. Stay tuned.
