This bug has now been confirmed in Word 2003, which was released about 22 years ago. So it's likely a "legacy bug" that has gone unnoticed since the early days of Word VBA.

What is the likelihood that Microsoft will want to fix the bug if I were to report it? Close to zero.


The bug probably doesn't impact too many users. (Although it does affect me!) Developers who have created macros that rely on selection.expand may have already incorporated workarounds. I just tested the "select sentence" command in Dragon Professional, and it is not subject to the bug. My guess is that Nuance developers knew about the problem with selection.expand and built the "select sentence" command to compensate for this limitation.
