If you open up the properties bar (control-e), and then select your comment box (I'm assuming Acrobat & the text commenting tool), you should be able to assign an outline to your paper/page color, and fill to none. Mine are behaving independently. You can get the same settings by right-clicking the comment box and choosing Properties. Let us know if this is NOT working in this way. (or if my assumption is wrong regarding your program and what you're trying to do).
