Mouse Without Borders

Steps to reproduce

When using MouseWithoutBorders with devices similar to a Wacom tablet, moving the cursor to the edge of the screen can cause the entire program to freeze and become unresponsive. At the same time, the mouse either cannot move at all or moves very sluggishly and erratically, making the whole system unusable, requiring a full reboot.

The MouseWithoutBorders process seems to have very high privileges. I cannot forcefully end the MouseWithoutBorders process using Task Manager, CMD, or an administrator-level CMD.
