HSV Window not moving

I can’t load a Mp4 or a gif to show you the problem since the file is too big.

Basically when i open the hsv window and try to move it in a position where it’s not obstructing my work, i can’t move it or resize it with the pen, but when i try with my mouse, everything works perfectly fine.

I don’t think it’s a big deal and i don’t know if it’s a bug or i am the one who is doing something wrong, just felt like reporting it.
