Necromancer Corpse Explosion at mouse left button

Once I bind the corpse explosion to the mouse left button the toon don’t walk at all until all corpses around explode. I just do 1 click and hold. Also I am unable to pick anything until all corpses are gone. Even if I click in an empty space. If there are corpses around I am trapped in the same situation.

I tried to bind the corpse tendrils to left button. In this case, the toon don´t walk at all.
I don’t use basic skills at all on any class but in necromancer I am getting these issues.

EDITED: If I bind the corpse tendril to mouse right button the toon don’t move for several seconds.

Thanks

bind it to a different button?

Nops. it should work properly on any button.
