Usage and Grammar

Q. I am editing online assessment for K–12. Writers keep using “Click OK when you’re done.” It doesn’t sound grammatically correct, but I can’t find any rule to the contrary. I’ve been changing it to “when you finish.” However, writers persist in using “when you’re done.” Is this grammatically correct?

A. Both are perfectly grammatical; I suspect you are worried that the usage is incorrect. There is a popular superstition, unconfirmed by dictionaries, that people cannot be “done” (like turkeys in the oven). Many writers therefore consider “finished” to be more proper.
