Roger, revdiablo and tachyon, Thank you so much for trying to cheer me up. As tachyon's reply is the last one at this time, I thought I just attach my reply here.

Not be able to have my vacation is not something 100% negative:

• Now I can continue hanging with you guys, if I go on vacation, I will 100% stop using computer, and just pretending that I never heard the concept of computer
• I can have a long vacation next year, with the add on of what I carried over
• Luckily I got it resolved, so the bug actually created joy for me, Thanks.

It is actually an interesting experience, as the place found the bug was not modified, so one can easily miss it during debug. In this case, it is not someone added a piece of buggy code, but missed a place that required modification. Bascially speaking, an old existing piece of perfectly right code, was turned into a bug. The challenge was to find the bug at a place that unlikely, plus the code was (is) very messy.

I talked with others that have looked at the code. The fact the code was messy largely reduced their ability to debug. The moment they opened up the code, they started to hate it, and I believe a kind of fear started to grow. Code that is less maintainable is not just technically less maintainable, but in fact is psychologically less maintainable.

Well indent your code! Code that is not nicely indented can scare people away! This is definitely not a small thing.

Thanks again, guys!
