Why is there a big check mark hovering over the list of my messages in my inbox?
See attached image. The checkmark flickers when highlighting messages under it, but it will return as i scroll through the list.

Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.
