Today I submitted my first bug fix in a Windows product. As might be imagined, the effort of fixing the bug was completely dwarfed by the process of accepting the bug, documenting the bug, building fixed binaries, checking in source changes, documenting the source changes, answering emails about documenting the source changes, etc etc.
Given how many people are actively working on Windows at any given time, all of this process is completely necessary, but still ... that's a lot of process.
On the bright side, I've now checked in code to the Windows base. Yay me! I will be signing autographs outside the stage door this afternoon.
