>PS: What surprises me is the ap I work on, after 8 years people still manage to find a bug here an there, and I wonder how it ever survived that long without anyone running that combinations of options, etc.

I know what you mean. I have an app that's been in use since 1978 (hey, that's longer than Mike H. has been alive <g>) and about once a year, I get a call on a problem. Given the history of the app, and the platform for which it was written, that's not too bad.
