No one has given me an answer for why that happened and I dont expect
one.
My point is, is that Microsoft is one of the biggest software producers in
the world and its still releases software with bugs and little niggles that
make you scratch your head or scream vulgar obsenities at it. In addition it
also crashes a fair bit and corrupts the odd file now and again for no
reason. As I have repeated, I could be an expert in Word but I would have no
control over these problems.
Most software that is released into the world has only 80% of its bugs
fixed. Software that is completely bug-free doesn't exist and if one
tries to create it, would never ship anyhow. The closest the industry
gets to bug-free software is the software that is used in life-critical
applications, e.g. by NASA. And even then, bugs are everywhere and
software bugs have cost ESA e.g. one rocket (Ariane 5), NASA at least
one $1 billion probe, almost jeopardized another NASA mission, etc.
The point is that for space applications the most expensive and
exhaustive software engineering practices are used and it still has
bugs. Bugs are a fact of life of computer programs, and bug-free
software only exists if the program is very small (you can probably get
10-100 lines to be bug free)
