so, i just had to get a new mouse, and the buttons on the side of it aren't working if i try to press them while also holding down the left or right click buttons. this has happened through two new mice now, so it's not just this one(i took the first one back to the store, thinking it was broken).
anyone have any idea how i could fix that? i tried looking through control panel, and there's only like 3 options for changing anything there, and it's not relevant to the issue.
this is just a shitty walmart mouse(ONN 2.4GHz wireless). but my last one(blackweb "wireless bluetrace mouse"(idk if that's the name, the packaging is long gone)) was a shitty walmart mouse, too, and it didn't have this issue.
