Middle Mouse Button Click and Pan stopped working

I recently upgraded to 1.4.04 and until then, I had been able to use the Middle Mouse button to click and drag the working area around. Now all of a sudden, it doesnt do that any longer. I tried downgrading to 1.4.03 and still am not able to pan w/ the middle mouse button. I can hold space bar and click and drag, that seems to work, but what happened to the middle mouse button functionality?

Can you confirm that the middle mouse button is working in other software?

Yes, the middle mouse button / scroll wheel works in other applications, and the scroll wheel works in light burn zooming in and out.

Nothing, AFAICT: it work here, admittedly on Linux rather than Windows.

Which suggests it’s not a LightBurn upgrade issue.

Perhaps one of those inscrutable Windows gotchas?

An “accessibility” helper kicking in without notice?

Working here on win 11

Try a different mouse to see if you get different behavior.

Same thing

Desktop, Laptop or both?

Both Windows 10?

Desktop. I don’t have a mouse on laptop.
