i love these two apps and thought they would work fine with each other. if i close out an app by sliding up from zephyr it will leave that app in the notification bar just black without full screen graphics of what the app is. but if i use the hold button instead of swiping up it works fine. also swiping left to right leave the multitask icon black. ive also had the springboard go black a few times. turns on again if i close the screen and open it again(power button). hopefully there is an update for these two to work together because its the best multitask and app switcher combo imo.
