Installing the Windows version of 1Password on a Surface Pro running Windows 8.1 interferes with the tablet writing function. Pen strokes disappear, or are inserted automatically before the letter can be completed. Uninstalling 1Password fixes the problem.
This was not an issue before upgrading to Windows 8.1. 1Password and the tablet writing function both worked fine under Windows 8.
Will there be a new version of 1Password released for Windows 8.1? Including an extension for Firefox? Not being able to install 1Password creates a major inconvenience not being able to copy and past robust passwords from 1Password running on the same machine as where I need to enter the password, or being able to log on to sites directly from 1Password. I have to retype them manually from my phone.
