It is usually preferable to group all items associated with each tab, 
so when switching tabs, you just hide one group and show another. In 
other words, the script sample from Judy above is reduced to a single 
hide/show pair for each tab.

When there is a larger number of objects and/or special handling is 
required when showing, it is indeed better to use multiple cards as 
suggested in another post, with special handling tucked into 
preopencard handler, for example. Tab button should be a 
single-object group with background behavior.

A small correction for Judy: the handler should be menuPick not 
mouseUp. And menuPick gets the name of the selected tab as the 
parameter so no need to call the selectedText of me. On the other 
hand, it is usually convenient to track the currently showing tab 
using a custom property of the tab button.
