Here are some settings that may help with the auto-attack disconnect issue:
these virtual key codes enable animation hack=
# These virtual key codes will enable the animation hack while pressed. This allows you to only use the hack with specific abilities.
# Multiple keys can be included by separating them with the "|" character.
# For example, if you set this to 97|98, both numpad1 and numpad2 will increase your animation speed.
# Please ensure you use the "how much to increase animation (attack) speed with keys" setting and set "how much to increase animation (attack) speed" to 0.
how much to increase animation (attack) speed with keys=0
# Same as "how much to increase animation (attack) speed" but only increases animation speed if "these virtual key codes enable animation hack" key is pressed.
Sometimes the ability activates before the animation speed is changed, resulting in a regular-speed ability. If possible, you can macro the key to enable the hack and then macro the key to activate the ability. In this way, the animation will always be changed in time.
