Every time in BL2 when I enter the shopping / inventory screen, I use the mouse wheel to scroll through the items. More often than not, it glitches out and gets stuck alternating between two items in the list. It does not respond to arrow keys or the mouse wheel anymore. It keeps alternating between two random items in the list. Switching between different tabs does not fix it. Sometimes exiting and re-entering the shopping menu also does not fix it. Seems like it happens randomly and goes away on its own accord.
Does anybody know how to fix this? Or why this is happening? I am playing BL2 on the PC.
