Common issues and possible solutions

• Dimensions/font size/location of elements are strange
  • This is often due to zooming/resizing of the browser. Try resetting the browser zoom to 100%, usually that should be enough
• Load error/white page: just refresh page
  • Likely due to loading files with the incorrect panel
• Region not being colored:
  • Usually due to color picker/eraser being on, so check if they are
