[Gameplay] some controls not working

i was trying out morgana 4 the 1st time. i tried clicking the shop, and the menue did' show up. I had no way of locking the camera. even if i died because it got me killed. i also need to double click to use the magic. to move the camera, i had to use the minimap. i also had to double click on the map.I only had this happen once but haven't tried playing again after this glitch.
