Just a cautionary note to those upgrading to 2012b. The installer is designed to wipe out your MM fonts and replace them with TT only fonts. There is no option to choose PS or TT. There is no way to customize the update at all! For those who use PS fonts be sure to make a copy of all of your MM fonts before running the installer, then run the installer, remove all the TT fonts, replace with the saved PS fonts. PITA!
