Ever had the cursor in your Hyper-V Virtual Machine (VM) not render as an Arrow or an I-beam but simply as a dot?

The fix is not at all intuitive. No amount of fiddling with the mouse settings seemed to have any good affect. But if you Save the VM’s state then immediately (or in your own good time if you prefer) Start and Connect to the VM again. The cursor display is restored to conform to the settings.
That’s all that is required. Not sure why the cursor display gets messed up in the first place. So, if you have the ounce of prevention, please leave a comment…
