Upfront - WYSIWIG Issues; Cursor position behaviour is inconsistent

I'd like to preface this email by saying I really appreciate what Upfront has to offer, we run a managed hosting company with thousands of Wordpress sites, and look forward to recommending this framework!

Onto my question - so a simple text box in Upfront in Chrome / Mac, what happens consistently for me, is that if there is existing text, where I place my cursor is not where the text will resume when I type. I need to cut and paste the text again, for the typing cursor to work again.

I hope that makes sense, and you are either aware of this issue or have replicated it before and can recommend a better work-around. Obviously in this particularly case, it makes editing existing text frustrating!

Thanks,
Luyen
