ISPT uses the unique Qivx Inc Menu design that combines normal menu items like "File" and "Help" with tabbed pages for the Periodic Tables, Property pages and Graphics. This revolutionary menu design, unique to Qivx software products, is attractive, easy to use and saves space. Choose a page view by clicking on a tab, or select from the other menu items as you normally would in other software.
One of the Tabs - the Tables tab, is actually dual function. Click on it to go to the periodic table view - it works like a regular tab - click on it when you are viewing the tables page and a drop-down menu will appear allowing you to choose a table style.
