I have confirmed this problem in the latest version in git (530049bc1dcc24c1178a29d99ca08b6dd08413e0). After the erroneous behavior the operating system issues a keyboard reset which prevents the mouse from functioning until the operating system is restarted. This seems to only occur if the PS2 mouse is being used as the input, the tablet input device doesn't exhibit this behavior.
