Ha. Years ago I filed a bug report on Excel (geometric growth in updates as DDM messages arrived). We had a paid bug-report-and-repair contract. Their response? "Nobody here knows how Excel works any more. This is never gonna get fixed." Also, I routinely used the debugger to launch Excel so I could debug my plugins. It faulted (null-pointer) several times during startup. Caught the faults and kept on plugging away. In my opinion, symptomatic of patch upon patch applied to old issues. We used to blame this on, at Microsoft only new code got you a good review and promotion. So only interns ever worked on existing products .And then they began hiring Juniors in college over the summer for a 90-day summer job to replace internships. After that absolutely nobody would work on old products. To top it all off, they a couple years ago folded their test groups into their Engineering groups. So now no testing gets done, or if it does the bugs can't stop the schedule. Because the testers are beholden to an Engineering manager instead of an independent organization. So now all Microsoft updates are tested simply by shipping them and sampling the bug reports.
