PROBLEM: Resources

Hi, anyone!

I've got a problem with my Delphi 1.0.

I'm using a form with Tabbed Notebook. There are 12 pages and each
page is full of components. There are more than 100 components
altogether.

Now, interesting thing happens:
In the beginning only the components that are on the current page
taking resources(the way it should be) but when I click on another
page, the new shown components take resources and the previous were
not freed, so after few clicks on different pages my resources are
coming to an end.

What can I do  to free resources of some components?

Jacob.
