I've tried searching the site, but couldn't find anything that answers my question.
Whenever I'm creating a new question or answer and I'm taking a while to type it all out since I'm still learning the MathJax system, very frequently the preview with all my nice MathJax formatting shows all the base code. Since I'm still learning MathJax, I really need to use the preview to see if it will render what I want it to look like. Every time this happens, I end up having to copy everything I typed, discard the question, then create a new question and paste the text, which will then render all the formatting. I usually have to do this about 5 times for each question or answer I create.
What would be causing this, and how can I fix it? Also, is there somewhere I can compose my question or answer and test the MathJax formatting? Preferably an offline program or something, to minimize any possibility that something about my browser is interfering with the previews on here.
