74 assassin need help with the skill on "FLAME DASH"

currently on the build "frostbolt + nova" with the assassin but having problems with the skill called flame dash. Currently, flame dash is set up on the right mouse click button and whenever i have two or more stacks and i use flame dash , the skill repeats itself automatically. This makes my character runs into the pack of monsters and sometimes makes me die . i tried using it on the mid scroll button but didn't feel comfortable with it . is there any other way i could avoid my flamedash going out twice by itself ??? i really dont click or press on the right mouse button for a long period of time..seriously,, this is making this game harder for me need help guys!

I think this is a bug with flame dash right now! If it's a huge issue, You could use Lightning Warp - Faster Casting - Less Duration instead until a fix comes!
