I use my left mouse key for forward movement and the sensitivity of the double click on the mouse initially had me dodge roll forward at the most inopportune moments.
I have since adjusted my double click delay and now i happens much more infrequent.
I had same issue... and turned it off for a while. Eventually it'll be worth turning back on and you'll want to fine tune the setting so it works for you.. you'll be at a disadvantage in PVP without it.
