Has anyone who has taken any of the NBME exams had issues running the exam in the last day or two? Using a MAC, and trying firefox, safari, IE 5.2.3 for MAC, the software barely runs and takes over 60 seconds to load each questions...I continually have to log out and re-login to get the exam to go. I have been on it for over an hour and am only up to question 14 of block 1 (CSSA #3)---FRUSTRATED? Already e-mailed NBME but haven't heard back... Anyone else with these issues?
