Has anyone figured out how to turn off auto-capitalization of certain words in the presentation editor?

I see how to disable the feature in SONGS (edit->options->song->song font->formatting), but there does not appear to be a similar option for Presentations. This means that we can't put up a question for the congregation like "How does God want me to submit to this?" without EW6 changing it to "How does God want Me to submit to this?"..which is almost antithetical to the spirit of the question itself

Click edit, options, presentation,
Click title font, formatting, and make the changes you need.
Repeat for Subtitle font and content font.

I tried that specifically in Presentation settings as I was also wanting to get rid of the "Me"s. It didn't work.

You are correct. This will be fixed in the next build we release, which will be fairly soon.
