Zoom freezes / disables mouse

[chrisholm]

When I open the Zoom app on my Windows 10 computer, my mouse freezes. Unplugging and re-plugging it in, plugging in a different mouse, or even reinstalling mouse drivers don't bring it back. I have to restart my computer to get the mouse to work again.

I am experiencing a similar problem using a KVM switch.  Starting Zoom the first time after a reboot, or starting a second Zoom with another Zoom session in progress, causes the mouse to freeze.  I'm using a Logitech Unifying USB Bluetooth at the KVM switch, so to restore it I have to unplug the unifying USB and then plug it back in to restore mouse functionality.  This issue started occurring in July or early August, so I suspect it is update related to either Zoom or Windows.  Any ideas on how to fix this would be most welcome.

Same problem here.  I am also using a KVM switch, but I'm not sure if that is relevant since it doesn't happen with any other applications.  Today, it happened to me twice -- I started the Zoom app and my mouse no longer moved (although the touchpad on the laptop still worked).  I rebooted and the mouse came back.  Then the same thing happed a couple hours later when I started Zoom again.  Not sure if this is relevant, but the Zoom app was launched from the PTC Wizard web page for parent-teacher conferences.  

Plugging in another mouse did not make any difference.

Just a little more information -- killing the Zoom.exe process(es) and then unplugging / re-plugging the mouse causes the mouse to start working again, no reboot required.
