I just clean-install Skyrim because I was bogged down by this problem for days. Upon a clean-installation the right mouse button or M2 functions correctly. (By default it's either block). I installed a few mods and it doesn't work anymore. The funny thing is even if I revert to the original state of having no mod, the problem persists. Also I ran into the same problem when using SKSE. Whenever I launched the game with SKSE, I ran into the exact same problem. The right-click in the game doesn't work. I gotta fix this but don't know where to look. Thanks. 2. I tried remapping the keyboard layout in the game but to no avail.
