PARAMETERS:
pi: Pointer to the AEEApplet structure. This structure contains information specific
to this applet. It was initialized during the AEEClsCreateInstance() function.
ecode: Specifies the Event sent to this applet
wParam, dwParam: Event specific data.
DEPENDENCIES
none
RETURN VALUE
TRUE: If the app has processed the event
FALSE: If the app did not process the event
