Hi Andrew,
Your having this problem because you have not a regular display.
Like many others with big screen, we play on icons and letters size to show it a little bit bigger. That is a problem for Cumulus since it takes a "snapshot" of your screen... but in your case all is bigger than what is supposed to be.
Your gauges page has the same problem, then you have to "unzoom" your display, or specify right size on all images on those pages.
Could be something to enhance in version 2.0! :ugeek:
