I recently had need for a text expander tool on a Windows 7 PC. After a little Google searching, I wound up using Adam Pash’s Texter. It’s free, simple, and lightweight. Unfortunately, after a few hours of use, I discovered that it had a “stutter.” By which I mean, when I typed ‘another’, I would wind up looking at either ‘aanother’ or ‘anotherr’.
Fortunately, there’s an easy fix. If you open up Texter’s preferences, you’ll see a setting for “Enable Universal Spelling AutoCorrect.” If you remove the checkmark beside that setting, you will find the “stutter” goes away.
