Mouse not switching weapons effectively enough - playing on Steam.

Sometimes in battle, weapon switching does not respond for maybe four turns. 

It means being in front of enemies waiting for the weapon to turn, while looking at the weapon. 

Meaning taking eyes of enemies and enemy attacks. 

Also what will happen is I will scroll the mouse wheel extra in a panic of the weapon not switching. Then switch past the weapon I want, and have to switch back.

It does happen out of combat too, and again may take four clicks of the mouse wheel to switch weapons.

My only grumble really. Excellent game.
