About file sharing to non-members

Most of my recipients that I send mail to have seen the Box application for the first time in their lives. When they click the download button on the Box page, the "Become a member" information message that pops up confuses my recipients. Even though they have clicked the download button and the file has already started downloading to their computers, and even though the window that opens says "Your file is being downloaded to your computer", they think that they cannot download without signing up. Please do not make this pop-up window so prominent. I am tired of constantly explaining it to my recipients and I have almost stopped using Box.
