Windmill failing and Enter Cooldown

So i read on the page that Windmill misses and enters cooldown during the time u get knocked back.

However for me, there is a second method where this happens as well (i am not sure for other ppl)

Melee Knockback the monster, move forward slightly in range to windmill the monster on the ground, activate windmill while spam clicking to activate windmill ASAP, then windmill gets canceled and enters cooldown.--Teoh 00:47, 21 July 2012 (UTC)

yeah. windmill is very glitchy now with the dynamic shiz.

I think it was because they removed the invincible frames...

The only time for me that WM "glitches" is during it's normal function. WM as a counter attack, but i load WM when i am getting hit and don't have enough composure, (meaning i am not stunned) therefore it uses WM in place of me getting hit.
