In the following example, if you do a dispose object of the window (objects[ST_WINDOW]), does it also dispose of the MsgPort, winAppPort, and List, selectmode, or do you have to free them separately with FreeSysObject(). (Sorry, I know this is messy.)

WORD radiodata;

struct MsgPort *winAppPort;
winAppPort = (struct MsgPort *)IExec->AllocSysObject(ASOT_PORT, NULL);
struct List *selectmode;
selectmode = (struct List *)IExec->AllocSysObject(ASOT_LIST, NULL);
IExec->NewList(selectmode);
IExec->AddTail(selectmode, IRadioButton->AllocRadioButtonNode(1,
RBNA_Label, "Difference",
TAG_DONE));
IExec->AddTail(selectmode, IRadioButton->AllocRadioButtonNode(1,
RBNA_Label, "Copy",
TAG_DONE));

objects[ST_WINDOW] = IIntuition->NewObject(WindowClass, NULL,
