Okay, so the update from within the program (1.6.1) doesn’t work. Assuming I can ever get this thing downloaded (the download is hideously slow), are we supposed to install OVER the previous version, or uninstall the previous version and then install the new one? If the latter, how do we preserve our customizations?
You can install 1.7.1 over your existing 1.6.1 installation if you wish, which will preserve your options and so forth. Do note though that there are some new features available from the format and main toolbars which won’t automatically display in this case, so you may want to go check out Tools > Customize Toolbars… The formatting preset button in the Format Bar is probably the one of most interest.
