Editing/responding to a thread

When I first started using Loomio I could type my responses with no problem, but now as I write I get to the bottom of the page and cannot see what it is I am writing: I can scroll to see it but as soon as I start to write it drops to the bottom of the screen. Very frustrating.
I also format some of my posts, using bullet points and paragraphs. This formatting is lost when I save it, though if I try to edit the formatted post is shown. Also very frustrating.
