It seems that there is a SIGNIFICANT decrease in the speed of the application of a highlight!
I do a lot of highlighting and up until beta 9 the speed from highlighting the text for the highlight and the actual application of the highlight was fine. After beta 9 there has been a rather significant (beach ball) slow down in the application of the highlight!
I would like to ask for a review of this. I have 8 gig of ram running Logos on a Mac with the latest Mountain Lion release with nothing else running. I have not tried this in Windows which will be my next adventure.
