I'm playing the Patch 1.12 version of Witcher 3 on PC using Windows 7 and an English input keyboard.
I'm having problems executing strong attacks with the default keyboard controls, specifically
Left Shift + Left Mouse Button
It works outside of combat, but as soon as I'm in combat, holding down Shift and clicking the left mouse button no longer works, Geralt just stands around doing nothing.
Is this a bug? Or am I not executing strong attacks correctly?
