I imagine this might be a device-by-device issue or just a weird Windows thing that's not easily solvable, but the extension appears to have no effect at all - even the demo .exe doesn't seem to do anything to the cursor.
The current release seems to depend on Microsoft C Runtime Redistributable (which is something you may or may not have installed if you’ve never installed Visual Studio or “large” videogames before). The next version won’t have this dependency, but also I’m rewriting the entirety of the code, so it’ll take a bit
