Usually, when the cleanups introduce bugs there are many other "suspicious" things. For me it's clear that you're learning the code and not just messing around. > >Paolo Many thanks for your approve. I really feel grateful for it. In fact, I am investigating the code and expect a deep understanding. But it's really a enormous, sophisticated and wonderful world, what I can do now is try to keep the code clean. Maybe I could introduce some useful features someday. Many thanks again. Best wishes.
