you have erased the files that deal with all that you mention it's not the cleaners fault you can not use it for what it is ,
it's not perfect but 99.9% perfect is close enough for me,
the rest is down to you study how to use it more carefuly.

I just want to say what a great little tool.
and i have had no problems with it at all.
i think most of the problems people have using it seems to be they're inability
to use computers properly.
