I was viewing my first lesson today, figured I might try one out. I began hearing this very faint dinging noise coming from my laptop. I never noticed it before, but right now, I'm in my room and it's very quiet. Anyway, I was getting ready to do a google search thinking it was something wrong with my laptop..but when I closed the lesson window, the dinging noise stopped. Is this something normal with the flash paper program? Has anyone else heard this before? If not, and you are using a laptop...do me a favor, and go to a quiet room and test it out for me. See if you hear the dinging sound when viewing a lesson on the flash paper program.
