I decided to switch to Thunderbird. However when I log on to the computer and click on the Thunderbird Desktop Icon or try to run Thunderbird from the Run command I get a message that says:
Thunderbird is already running, but is not responding. To open a new window, you must first close the existing Thunderbird process, or restart your system.
However, according to the Task Manager, Thunderbird is NOT running. Rebooting has no effect. My wife does not get this message when she logs in, her email (using Thunderbird) is working fine.
Can someone help?
