Nisus Writer 5.1.3 Updates
Updaters are available that patch U.S. or British versions of Nisus Writer 5.1.x to create version 5.1.3, which fixes a Measurement Preference dialog bug that disabled the lower half of the dialog.

If updating from 5.1 or you have the 5.1 Floating Tool Bars Tool, you should download the new Floating Tool Bars Tool as well.

IMPORTANT: Choose the updater for the "flavor" of Nisus Writer (U.S./British) you're using. The 5.1.x flavor updates all versions of 5.1. If you're not sure which you have, check which dictionaries (U.S. English or British English) were installed by default.

You can update the Institutional Edition here, too.
