I received an requirement from my boss to display more than the default 6 rows in the Edit in Datasheet view of data lists. I hate this beast (ie. datasheet) because it is really unpredictable (see my previous posting).

This offcourse makes the change global for all Datasheets and very exposed to future updates from Microsoft. So add it to your list of things to check after next upgrade… 😉
