IMO it's a bad idea to minimize forms together with the main form. 
Better the application should minimize, automatically hiding all owned 
forms.

The placement of minimized forms varies across window managers. Win32 
(or Delphi?) puts them onto the bottom of the screen, so that every 
window can be restored from there. This behaviour may be related to the 
implementation of MDI windows, where minimized MDI childs reside on the 
bottom of the MDI window. Other window managers require a window menu to 
restore minimized form. In no case forms should become part of the task 
bar, this one is reserved for tasks (applications) - as the name says.
