Hi All,

The tutorial at

http://java.sun.com/docs/books/tutorial/applet/overview/lifeCycle.html

Says

"When the user leaves the page -- for example, to go to another page --
the applet has the option of stopping itself. When the user returns to
the page, the applet can start itself again. The same sequence occurs
when the user iconifies and then reopens the window that contains the
applet. (Other terms used instead of iconify are minaturize, minimize,
and close.)"

Well, not what I'm seeing! I modified my test applet to show paint
events as well an init, start, stop and destroy and paint is the only
one that gets called as the applets are scrolled in and out of view.
Only looked at in in IE though.

In reality I can live with the behavior I'm seeing, but it would be so
nice if worked like the tutorial...

Thanks,

Marcus.
