Fixed a huge problem for a client by changing an 'OR' to an 'AND'. Took 3 days to determine what was going on. Bug hunting is sort of fun, the moment when you're just about to find the problem is the most exciting, better than the joy at fixing the problem, or the unravelling of the workings of the code - when everything falls into place and you slowly zero in on the problem..ah nothing like it.
Also, fell behind on C++ learning so wasting my lunch break on that. =)
