I’ve had that experience myself and I can totally blame Microsoft. I’ve been coding with FoxPro for over a year. In those days you could easily code for hours and save your work only at the end. FoxPro had a well designed dialog that asked you “Save file.ext” with default on Yes

Then Microsoft acquired FoxPro, you couldn’t tell before/after by design, but first MS FoxPro UI change you could find was the dialog was changed to “Quit without saving”.

Nice (at least I’ve only lost a full day of two programmers work)
