Oracle VM Console Mouse Cursor does not move AT ALL. Worked fine previously.

I have a problem where the Mouse cursor suddenly does not respond at all in the novnc Window opened from the

"Virtual Machines" Perspective in "Oracle VM Manager".

The cursor comes up dead center and never moves.

It always used to work. The laggy and out-of-sync issues where something I lived with until I learned to set the

"Mouse Device Type" to USB TABLET.

Now it suddenly does not work at all.

AFTER It failed I tried the following.

I tried adding the usbdevice='tablet'.

I tried variations of the VM Config for "Operating System", "Mouse Device Type", "Domain Type" to no avail.
