The idea-generator 
for this post is another post about bug in Excel 2007. It is not small bug, it is 10 000 – 65 535 = 34465 of something (dollars or euros perhaps). Anyway, my post is not about Excel. When I heard for this Excel bug I asked some of my in-love-with-microsoft-friends a question: ‘is there some microsoft’s program without bugs?’. There was many answers (there is no bug less software etc…), but one of them says that there is one program that is 100% bug free – NOTEPAD!
