Re: So many problems...
The registry is where all possible errors and mistakes can occur. Linux, does not ave a registry (I think), which makes it Okay, but it is a pain. MAC is where Windows was based. Bill stole the first Macintosh's first graphical OS and he worked himself from that. MAC is stable, but it looks like MAC comes from linux (usr folder in install, sudo install)
Really bizzare OSes. Older graphical OSes, like the ones yopu have not seen are the ones stable.
