Hi,
I use inverted primary mouse buttons (changed in windows mouse settings) so left click and right click are swapped.
This change doesn't pull through to the game. While in the menu and in the inventory my right click is still the primary mouse button.
I have just purchased the game and found this is the case and there are no in game settings to rectify this. It is pretty game breaking for as It is unnatural for me to drag and drop with right click while in the inventory and slows me down considerably.
After searching online it appears this issue was reported during .60 and was fixed.
