There were not a large number of notes, I think there may have been some other things going on, my performance has been better except one thing. Often times when I go to click on a note to enter text or update text, it can take a number of mouse clicks before the cursor focus actually happens for me... this MAY still be laggy response, or it may be something with my browsers/computers (I am using Firefox and Chrome on a well equipped Mac OS). Do others experience this as well? Just trying to determine what may be at fault here....
