[DUG]: How do you explain this?

* dropped a panel1 on the form * dropped panel2 on panel1 * dropped panel3 on panel2 * then programmatically set the parent of panel2 to panel3. * compiled and run now here goes. once i changed the parent of panel2, its gone ! i closed the application, app is gone on the taskbar but my delphi hasn't returned yet (i ran it on the ide). delphi says its still running. looked on the task manager, and there it is on the processes tab. i reckon its still running, doing an infinite loop. panel2 and panel3 freeing each other recursively. what gives?
