I posted a reference (see Post #813842) to a registry key that has three elements separated by a dot:

Word . Document . 8

When written without the spaces, the board lower cases the word Document:

Word.Document.8

I tried to edit my post, but the underlying post text already is correct. there is something about the display of the post that is causing this.

Maybe this is to make domain names prettier? Because accuracy is more important, I suggest we turn off this feature, whatever its purpose.
