Le pointeur de la souris se déplace quand on appuie sur les touches fléchées ?

Je rencontre un problème étrange on my W10 computer, for a few days my arrow keys have been "driving" my mouse pointer. Pressing the left arrow key will move the pointer a few pixels left, etc.

The first thing that came to my mind was "Oh well, I must have enabled Mouse Keys inadvertently". But Mouse Keys use the numpad and even then, it's not enabled. Rebooting doesn't help, but ***J'ai remarqué it doesn't happen if the current window is ran as another user (Administrator)*** or if it's the Gestionnaire des tâches, which suggests the event filter that's catching the key press events is only active on my UID.

*J'ai essayé killing various processes but J'exécute out of ideas. Quelqu'un pourrait-il suggest some fix for this strange behaviour?*

Tried killing all running processes on my PC till the problem went away and I can now say for sure the culprit was...

## Microsoft Paint

(classic Win32 one)

Apparently it's got a feature that allows moving the mouse pointer using arrow keys, and pour une raison quelconque sometimes it doesn't stop listening when the window loses focus, so Paint was running in the background since Je souvent use it and it was still doing its job of moving the mouse.

This also explains why the problem can persist **after a reboot**: when you reboot Windows while Paint is running, Windows will automatically "save your work" and **reopen Paint** at system boot, **causing the bug again**!
