So I was playing Dishonored earlier today, when for some reason I tried to right click in game and it didn't work, despite that it had worked not even 5 seconds earlier. After closing the game, it seemed like the mouse buttons had switched their functions (M1 did M2's job and the other way around). I went into mouse options and toggled it back (even though it wasn't changed, i swapped it from right handed to left to right again). Now mouse 1 seems to work correctly, but mouse 2 is completely unresponsive. The trackpad on my computer's mouse buttons also seemed to have stopped working in their entirety.
Have any of you guys had this problem before? I think it might be a physical problem with the mouse, but after i opened it up and checked it all looked alright.
