I recently ran into something on this website that I haven't experienced before. I was attempting to answer a user's questions on summations. The index of the summation was a lowercase "i". I noticed whenever I attempted to type this letter, the "i" kept getting capitalized.
Even during this post, it's capitalized both occurrences. The only way I've been able to keep it lowercase is to type it, then delete it and retype it. If this is a new feature, I recommend it's disabled. Heaven forbid I answer someone's question on complex numbers. I may need to resort to using the engineering notation of using "j" instead of "i".
The other possibility I can think of (if this isn't a new feature to this website) is a recent update to IE 11, which supposedly failed. The version is showing up as 11, but I see no autocorrect feature under internet options.
Also, I apologize if this is the wrong place to ask about something like this. From what I can see, there is no help document about what questions should be asked on the meta site.
