Hi Mark E. - We're not aware of any incompatibility issues; we're web-based, so I'm not sure what wouldn't work with HTML5 browsers. Since you are writing a paper, you may also want to explore our Wiki for more information on our site, there is a ton of info there! Since I've answered your question, I will go ahead and close the post as well, feel free to start a new thread if you have any other questions.
