cursor showing

Hi,

after playing for a while the cursor is displayed with the hand of evil

after playing for a while to try and find the trigger, I found out that it usually appears when I press the vein of Evil button and scroll up at the same time.

this doesn't happen at the beginning of the game, (I tried) but happens as the game progresses and you have built all the dungeon and are ready to attack. usually, there is heavy activity with minions at that time. the game doesn't lag in any way when it happens.

game version 1,3

OSX 10.11.5
