Running the GOG version with the 1.03 patch.
The issue is I can no longer bind my side mouse buttons to any function within the game. I can bind LMB/MMB/RMB without issue, but none of my 3 side buttons work. Pre-patch they worked fine. I am using a Logitech M705 Mouse that works flawlessly outside of PoE in every regard. Please look into this issue, thanks.
