Hello Stata Folk

When I enter two spaces in the do file editor (i.e. press the space bar twice) the editor automatically enters a period.

I imagine this is a setting along the lines of when using a word processor where it "helpfully" adds corrections to common typos. This is not helpful in do files though. Can anyone advise me how to turn this setting off? Hopefully this is an easy fix and something that I haven't just found the right keywords when searching the forums.

Thanks in advance
