it's all as it should be. I have not had such a mouse, maybe it's me, but I'll go with the two buttons left of the mouse to scroll back and not clear. constantly I get it even if I do not want it, the nerves a bit. and stupid it, which remains the mouse is active even when the PC is in standby, to think I be so, because you can hibernate fetch PC from the mouse. Anyway, price-performance ratio!
