Dunkmaster Darius and client cursor issue.

There is a strange bug that seems to only happen with Dunk-Master Darius. While playing aram i received DM Darius from the RP boost. During gameplay if I used a spell the cursor would either change to the red sword permanently or the finger pointer. It would get stuck like this for quite some time. The only way i could get rid of it was to press "G" on my keyboard and issue a ping command. The issue, the REAL issue is that it becomes very difficult to target champions and minions when this happens. And if you manage to do so your character moves behind the minion before it attacks it, instead of at the closest range. I don't know if this happens with any of his other skins but so far I've had two instances of this happening and both times on the Aram map. I tried taking screenshots but forgot the client doesnt allow you to do so in full screen.
