Since yesterday's update components have stopped redrawing properly when I move them about. Everything worked perfectly on the previous version but now only the ratlines and silkscreen component name move in realtime when I drag a component about. In order to see where the component has ended up, I have to either drag the viewport about slightly or go to a different zoom level, at which point the component redraws. This makes it very difficult and time consuming to place parts accurately. I know Firefox or Chrome is better. Internet Explorer isn't my choice of browser but I'm stuck with it, and easyeda did work fine before yesterday - here's hoping you can fix it....
