How funny, I also started up HK before making my comment, just to check! We might just be interpreting the same detail differently. Whatever the case, it does have something of an effect. I absolutely agree, mechanical polish is something that could take a long time.
I felt what you meant when you recommended using a game pad. I didn't have mine handy to pull out, but I guess it's a lesson in controller support. I didn't even think of it! Sounds like DrManatee had some good ideas and feedback there.
It was a pleasure!
