PrimeLister sometimes stops working because it is paused by Chrome when you minimize the Poshmark tab or send it to the background. A workaround to this is to keep Poshmark in a separate window or tab in the foreground. It is suggested to keep the Poshmark page in a separate window and drag this window off to the side of your display so it will be visible only on a small portion of the screen. Doing such, you can use your computer to do other things on the rest of your screen at the same time while PrimeLister is running.
