Hi there - Jean will release the latest version of this module shortly:
Horoscope-Medieval-Medieval Traditional Chart: v.9.146 - tabbed version, many improvements and bug fixes, this version is designed for 1920 x 1080 (full HD) monitors.
Users should update if they use this module regularly.
If you are using a laptop with a 1366 x 768 pixel size, there will be limitations with the display that are difficult to overcome, due to the complexity of the graphical display on some tabs. I will continue to work to overcome this, but many of the tabs should be useable.
Thanks. Ed
