Hello there Jimmoe. We have read your message. We try to help you.

A old mouse or a brand new one? Oké that sounds odd. Is this problem with your mouse that is wired or works on infrared a long term problem or did it appear suddenly by using it? Drivers for the mouse are available from the company it’s made. Usb-a mouse? Or a thunderbolt mouse.

What is the mouse his factory name can I ask that? Can you check if you’re OS is infected?

The mouse is fairly new, about a year old. It is a Logitech m525. The issue is unique to Thunderbird, and to TB's message pane; with no other program or app do I experience this peculiarity.

Hello there we have read your message. Can we still help you?

There are drivers in the Logitech site fill in your type of mouse NR.On google You have got a special function mouse. On that site there s a download page with explanation.

Logitech wireless m525 Mouse driver

The OS i use is linux. There are no drivers for the mouse at Logitech.

Once again: The issue is unique to TB. Only TB. And only in the message view pane. The mouse wheel works as expected everywhere else, in all other apps.

день сумо, this is obviously a Linux user (OpenSuse) and not a Windows user as was mention in the first post. Your link only has drivers for Windows and one for Chrome OS.
